It should okay to push this via the hsx/hotspot-gc forest, assuming of 
course that the tests in its jdk repository are actually used for the 
testing that you mention. One thing to know is that 
test/java/lang/management/MemoryMXBean/CollectionUsageThreshold.java is 
on the exclude list (see jdk/test/ProblemList.txt) so the test should 
not be run (so in Oracle this means it is excluded in JPRT, in testing 
of jdk8/tl, etc.). If you are happy that the test is now stable then it 
would be good to remove it, but I think you might want to check 7067973 
in case that issue and failure mode still exists.
