Trace Compass/News/NewIn61


JavaSE-11 Requirement

In the Eclipse 2020-09 (4.17) release, some plug-ins that are dependencies of Trace Compass (specifically, CDT and the Eclipse help plug-ins) have changed their required Java execution environment to JavaSE-11.

This means that, in order to run the Trace Compass plug-ins with the tracecompass-e4.17 target, or to run the Trace Compass 6.1.0 RCP application (which is built with the e4.17 target), the user must have a Java VM that is JavaSE-11 or later installed.

Note that the Trace Compass plug-ins themselves still have their required Java execution environment set to JavaSE-1.8, so it is still possible to run the latest Trace Compass plug-ins with this Java version, if an older target (e4.9 to e4.16) is used to build.
