Comments
The referenced java.lang.management.ManagementFactory does not exist in a minimal VM. The suggested fix is to exclude this test for minimal VM.

Moving the integration_blocker label to JDK-8185879. Update: This test is only present in JDK10/hs. That makes this an integration_blocker so I'm putting back the label.

The fix that added this test: JDK-8177968 is only in JDK10/hs so that makes this bug an integration_blocker.

the test should either declare its dependency on java.management module w/ @modules tag or be rewritten to get rid of this dependency.
