JDK-8076995 - gc/ergonomics/TestDynamicNumberOfGCThreads.java failed with java.lang.RuntimeException: 'new_active_workers' missing from stdout/stderr
Description
There are a number of tests failing because of g1 is not supported. Such tests prints a warning on start:
  Java HotSpot(TM) Embedded Server VM warning: G1 GC is disabled in this release.
and continue execution.
But fail because they test G1 specific behavior, which is not present.


List of such tests:

Seems i found a problem for hotspot tests. There is a TEST.groups format violation, which should be fixed. A group "needs_g1gc" definition has missed "\" at the end of line with gc/ergonomics/TestDynamicNumberOfGCThreads.java

ILW = High (crash), Low (only embedded is affected), Low (do not start such test using jtreg group) = P4
