The header of the CollectionUsageThreshold.java tests now looks as:

/*
 * @test
 * @bug 4959889 6992968
 * @summary Basic unit test of memory management testing:
 * 1) setCollectionUsageThreshold() and getCollectionUsageThreshold()
 * 2) test notification emitted for two different memory pools.

So this test is no longer applicable for VM SQE testing. Because with each run a GC to use is specified.
As the result this test will always fail with:

Conflicting collector combinations in option list; please refer to the release notes for the combinations allowed
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
result: Failed. Unexpected exit from test [exit code: 1]
