Known issues

BlackBerry UEM 12.9 uses Google Web Toolkit (GWT) version 2.8.2. GWT 2.8.2 restricts access to some JAXB libraries. If any of your custom UEM plug-ins use restricted JAXB classes, the plug-ins will not be able to access these classes when running in UEM version 12.9. As a result of this change, it is recommended that you update any affected UEM plug-ins to remove JAXB-related dependencies from GWT code.

For more information about this GWT change, see JEP 320: Remove the Java EE and COREBA Modules.

When you start the process to integrate your Eclipse development environment with the local UEM installation, a window prompts you to choose which UEM services to stop so that you can complete the integration. After you select the services and click OK, the integration process does not stop the services. (2195939)

Workaround: In the Windows Services, stop the UEM services manually.
