All,

I've updated the change quite a bit based on feedback from Bengt and 
Christian.

The class JmapLauncher has moved to the newly created gc testlibrary. 
This gc testlibrary, com.oracle.java.testlibrary.gc, is meant to contain 
utilities that can be used by all the gc jtreg tests. If there are code 
that is of interest for additional tests, then code can be easily be 
moved from the gc testlibrary to the general testlibrary.

I have updated the ClassMetaspaceSizeInJmapHeap.java to make use of this 
new gc testlibrary.

Please see new webrev at:
http://cr.openjdk.java.net/~ehelin/8009408/webrev.02/

Thanks,
Erik
