This test rarely fails in the past on some configurations but was never a problem listed, and according to the history of CI, it fails 2 times on its own this year.
There are two possible reasons for the failure: 1. At that time we had a memory leak, which was fixed. 2. The test works too fast and it was not enough time for GC to eliminate 1000 windows. To make the future evaluation simpler I enhanced the test and make it stricter, see some comments inline. ------------- Commit messages: - Update OwnedWindowsLeak.java - Update OwnedWindowsLeak.java Changes: https://git.openjdk.java.net/jdk/pull/1105/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=1105&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8225116 Stats: 26 lines in 1 file changed: 4 ins; 12 del; 10 mod Patch: https://git.openjdk.java.net/jdk/pull/1105.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/1105/head:pull/1105 PR: https://git.openjdk.java.net/jdk/pull/1105
