Fails like this: $ CONF=linux-x86_64-server-fastdebug make run-test TEST=java/lang/management/ManagementFactory/MXBeanException.java TEST_VM_OPTS="-XX:+UseShenandoahGC" ... java.lang.NullPointerException: Cannot invoke "java.lang.management.MemoryPoolMXBean.setUsageThreshold(long)" because "MXBeanException.pool" is null This test tries to find the pool that is `!p.isUsageThresholdSupported()`, and for Shenandoah there is no such pool. Likewise with ZGC, which is already filtered. Additional testing: - [x] Affected test is now skipped for Shenandoah - [x] Affected test is still skipped for Z - [x] Affected test is still passing for G1 ------------- Commit messages: - Fix Changes: https://git.openjdk.java.net/jdk/pull/5757/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5757&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8274522 Stats: 1 line in 1 file changed: 0 ins; 0 del; 1 mod Patch: https://git.openjdk.java.net/jdk/pull/5757.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5757/head:pull/5757 PR: https://git.openjdk.java.net/jdk/pull/5757
