Reducing the amount of glucose and carbohydrates absorbed during digestion. Benefits of Java Burn Java Burn offers a range of benefits to support your weight loss and overall well-being: Enhanced Metabolism: Java Burn includes ingredients like Chlorogenic Acid and Green Tea Extract that boost metabolism, increasing calorie burning and aiding in effective weight loss.Fat Burning: Natural compounds such as L-Carnitine and L-Theanine promote the breakdown of stored fat, converting it into energy and reducing body fat percentage while preserving muscle mass.Increased Energy Levels: The blend provides sustained energy without the crashes associated with caffeine, keeping you active, alert, and motivated throughout the day.Appetite Control: Ingredients like L-Theanine help suppress hunger and reduce cravings, supporting a calorie-controlled diet essential for weight management.Immune Support: Vitamins B6 and B12 enhance the immune system with antioxidant and anti-inflammatory properties, ensuring overall health during weight loss.Better Sleep Quality: Java Burn promotes relaxation and stress reduction, leading to improved sleep quality, which is vital for metabolism and hormonal balance.Mental Clarity: Components like L-Theanine enhance focus, concentration, and mental sharpness, keeping you productive and clear-headed.Overall Health Support: With its natural ingredients and comprehensive benefits, Java Burn supports long-term health, making it a valuable addition to a balanced lifestyle.Regulates Blood Sugar Levels: Ingredients like Chromium and Chlorogenic Acid help stabilize blood sugar levels, reducing insulin resistance and preventing fat storage, which is crucial for weight management and metabolic health.Supports Detoxification: Antioxidants in Green Tea Extract and Chlorogenic Acid aid in flushing out toxins, improving digestion and ensuring optimal metabolic function for long-term health benefits.Improves Hormonal Balance: Java Burn helps regulate hormones associated with appetite and fat storage, such as insulin and leptin, creating an ideal environment for sustainable weight loss and overall well-being. How Java Burn Works Scientifically ? Java Burn works through a scientifically supported mechanism that focuses on boosting metabolism, burning fat, and regulating appetite using a blend of natural ingredients. At its core, the supplement stimulates thermogenesis, a process in which the body burns calories to produce heat. This is achieved with the help of ingredients such as green tea extract and L-Carnitine. Green tea extract contains catechins, which are known to enhance calorie burning, while L-Carnitine supports the breakdown of stored fat into energy. Together, these components ensure that the body burns fat effectively while maintaining energy levels throughout the day.The supplement also plays an important role in regulating blood sugar and insulin levels. Chromium and chlorogenic acid are key ingredients in this process. Chromium improves insulin sensitivity, ensuring that glucose is efficiently utilised for energy rather than stored as fat. Chlorogenic acid, sourced from green coffee bean extract, minimises sugar spikes after meals and reduces excessive carbohydrate absorption. This combination not only promotes

Upgrade, test, and release your custom connectors for Java 17 to ensure compatibility within the MuleSoft ecosystem. Ensuring this compatibility is crucial because running an incompatible connector can lead to runtime failures, decreased performance, and security vulnerabilities that could impact your app’s stability.Before You BeginBefore upgrading and testing your custom connector for Java 17, you must be familiar with the following considerations:Target compilation levelIn Mule 4.9.0 and later, you can compile any Mule project for Java 17 or lower. Additional dependencies must be compiled for Java 17 or lower.If you compile for Java 17, the mule-modules-parent should be upgraded to version 1.9.0 or later. The connector’s minimum Mule version will also be 4.9.0, ensuring compatibility only with Mule 4.9.0 or later. See Specify Java Compatibility.If the mule-modules-parent version is earlier than 1.9.0, the bytecode level for the connector and its additional dependencies must be for Java 8. You can’t use language features from Java 11 or Java 17.Unsupported directivesDon’t set -add-opens or -add-export directives. These directives are not allowed in CloudHub or Runtime Fabric, require managing them for each connector across all environments, and introduce a backward compatibility burden, complicating future Java upgrades and potentially enabling security vulnerabilities.Minimum Mule versionIf your custom connector is running on Mule 4.5.x or earlier, you can’t run Java 17 tests that extend the MuleArtifactFunctionalTestCase, but you can still run Java 8 tests.To decouple the minimum Mule version when running tests, add the -Dmunit.jvm parameter to use Java 17 as described in Test Your Custom Connector with MUnit.Upgrade Your Custom Mule SDK ConnectorsUpgrade your custom Mule SDK (Java SDK and XML SDK) connectors to Java 17.Upgrade Third-Party LibrariesYour custom connector likely relies on third-party libraries, so it’s important to ensure they are compatible with Java 17 as well. Even if your custom connector passes tests, it is still important to deliver secure and reliable software. If a critical bug or vulnerability is found, you must upgrade to a fixed version. Using up-to-date libraries that explicitly support Java 17 makes this process easier and more reliable, as the vendor has already tested them on Java 17.Upgrade the third-party libraries of your custom connector to be compatible with Java 17:Java EE librariesMule 4.6.x exposes Java EE libraries differently than earlier Mule versions. You must add the BOM dependency to your custom connector and, if applicable, exclude the provided conflicting library. You can also add the libraries in the BOM dependency separately. 4.6.0 org.mule mule-javaee-runtime-bom ${muleJavaEeBomVersion} pom import External librariesUpgrade external libraries, which are third-party libraries that are not bundled with your custom connector. Some examples include a JDBC driver, JMS broker client, or Groovy runtime. The following example shows a JDBC driver external library configuration:@ExternalLib(name = "MySQLJava 17 Features - Java Guides
You have MUnit dependencies, such as munit-runner and munit-tools, replace the version for each dependency with the ${munit-version} parameter.Replace the version for each connector dependency with the Java 17 compatible version of the connector.Open a terminal window in the root of your Mule project and run the following command. This command displays the earliest versions of Mule runtime, MUnit, and the Mule Maven plugin that are compatible with Java 17.mvn -f pom.xml -s ~/.m2/settings.xml -Dapp.runtime=4.6.0 -Dmunit.version=3.1.0 -Dmule.maven.plugin.version=4.1.0 -fae testYou can now see if your connector is compatible with Java 17. For more information about running MUnit tests, refer to MUnit.The Mule runtime version you use determines the version of the mule-modules-parent. For example, if you use Mule runtime 4.6.0, you must use mule-modules-parent 1.6.0. Minor versions maintain a correspondence, such as Mule runtime 4.1.0 with mule-modules parent 1.1.0, Mule runtime 4.2.0 with mule-modules-parent 1.2.0, and so forth.Java 17 is supported with Mule runtime 4.6.0 and later. However, a connector can be compatible with both Mule 4.3.0 and Java 17 simultaneously. If your connector must be compatible with Mule 4.3.0, its mule-modules-parent version cannot exceed 1.3.0. You don’t necessarily need to use mule-modules-parent 1.6.0 for your connector to be compatible with Java 17. Using mule-modules-parent 1.6.0 is specifically required to leverage other features from the Mule runtime 4.6.0 in the connector.Release Your Custom ConnectorAfter you update your code and your tests are green, you are ready to release a new Java 17-compatible version of your custom connector.To communicate Java 17 compatibility, generate metadata for Java compatibility of your custom connector by adding or upgrading the custom connector mule-sdk-api dependency to the latest version: org.mule.sdk mule-sdk-api 0.10.1For Java SDK, add the @JavaVersionSupport annotation in the same class as the @Extension annotation and include the JAVA_17 value, for example:You don’t need to add any annotations for XML SDK because XML SDK modules are Java 17 compatible and inherit the property automatically.@Extension(name = "Database")@Operations(...)@JavaVersionSupport({JAVA_8, JAVA_11, JAVA_17})public class DatabaseConnector {..}In Mule 4.5.0 and later, custom connectors that don’t specify the @JavaVersionSupport annotation are assumed to be compatible with Java 8 and Java 11.You can mark your custom connector as compatible with Java 17 only; however, you must ensure that no adoption or backward compatibility issues exist.When you deploy a Mule app, Mule verifies that all modules in the Mule app are compatible with the Java version. If Mule finds an incompatibility, Mule throws an error and the application does not deploy.If you receive an error message specific to an XML SDK based connector, such as Extension 'module-error-handler-plugin' does not support Java 17. Supported versions are: [1.8, 11], this means that your Mule app still contains some connectors that are not compatible with Java 17. To.
