[jira] [Commented] (YARN-9513) [JDK11]

ReferenceError: "GcCountPS_Scavenge" is not defined in at line
number 1

Adam Antal commented on YARN-9513:
----------------------------------
I got a chance to run this test on multiple JDKs, and it turns out that it has nothing to do with being the OpenJDK. The names of the GCs have been changed since Java 1.9, so we should only do a version check.
Tested patch v1 against the following JDKs:
- 8.0.202-zulu
- 9.0.4-open
- 9.0.7-zulu
- 10.0.2-open
- 10.0.2-zulu
- 11.0.2-open
- 11.0.3-zulu
They all passed on my local.
I also checked other occurrences of {{GarbageCollectorMXBean}} and it looks like it is mostly used for calculating GC-related metrics, but the names are never hardcoded besides the invariants.txt, so it is not expected to cause issues anywhere else.
