Hi everyone, ticket: https://bugs.openjdk.java.net/browse/JDK-8236259
The fix itself is quite straight forward. It basically just removed the listener which causes the leak. The unit-test for the fix is a bit more complicated. I added a library JMemoryBuddy https://github.com/Sandec/JMemoryBuddy (written by myself), which simplifies testing for memory leaks. I think there are many places in the JavaFX-codebase that could highly benefit from this library. It could also simplify many of the already existing unit tests. It makes testing for memory-leaks readably and reliable. It would also be possible to just copy the code of the library into the JavaFX-codebase. It only contains a single class. I also had to make a method public, to write the test. I'm open to ideas, how I could solve it differently. ------------- Commits: - c4da2e7b: JDK-8236259: MemoryLeak in ProgressIndicator - DeterminateIndicator doesn't get collected Changes: https://git.openjdk.java.net/jfx/pull/71/files Webrev: https://webrevs.openjdk.java.net/jfx/71/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8236259 Stats: 45 lines in 4 files changed: 41 ins; 0 del; 4 mod Patch: https://git.openjdk.java.net/jfx/pull/71.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/71/head:pull/71 PR: https://git.openjdk.java.net/jfx/pull/71
