Changes in This Release

Java Module 2.0 includes these changes.

Java Module (and its dependencies) are now compilable and compatible only with Java 17.
To align with modern development practices and ensure continued compatibility with secure and supported libraries, Java Module is upgraded from Spring 5.x to Spring 6.x.

Upgrade Prerequisites

Before you perform the upgrade, you must create a backup of your files, data, and configurations in case you need to restore them.

Upgrade Steps

Follow these steps to perform the upgrade:

In Anypoint Studio, right-click the project and select Manage Dependencies > Manage Modules.
Select Java Module - Mule 4 and click Update version.
Click Apply and Close.
Verify that the Java Module dependency version is 2.x in the pom.xml file in the Mule project.

Alternatively, you can manually update the Java Module dependency version in the pom.xml file in the Mule project, or simply add the updated module to the project.

Verify the Upgrade

After you upgrade the connector, follow these steps to verify the upgrade:

In Studio, verify that there are no errors in the Problems or Console views.
Verify that there are no problems in the project pom.xml file.
Test the connection to verify that the operations work.

Troubleshoot

If there are problems with caching the parameters and caching the metadata, try restarting Anypoint Studio.

Revert the Upgrade

If it is necessary to revert to the previous version of Java Module, change the Java Module dependency version 2.x in the project’s pom.xml to the previous version.

You must update the project’s pom.xml in Anypoint Studio.
