Could I have a review of change that fixes an intermittently test failure. The classes are garbage collected before they are being recorded by JFR. The fix is to add a hard reference to them. I also added a call to System.gc() to ensure the test is not sensitive to garbage collections. Testing: test/jdk/jdk/jfr/ and test/jdk/jfr/event/runtime/TestClassLoaderStatsEvent.java Thanks Erik ------------- Commit messages: - Initial Changes: https://git.openjdk.org/jdk19/pull/158/files Webrev: https://webrevs.openjdk.org/?repo=jdk19&pr=158&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8291524 Stats: 10 lines in 2 files changed: 4 ins; 0 del; 6 mod Patch: https://git.openjdk.org/jdk19/pull/158.diff Fetch: git fetch https://git.openjdk.org/jdk19 pull/158/head:pull/158 PR: https://git.openjdk.org/jdk19/pull/158
