This mostly looks okay but there are still a few tests being penalized 
with a long list of classes in their @build tag.

Take LotsOfUpdatesTest as example. It's a trivial test to launch a child 
VM with `ulimit -n` set to a small value. Its use of ProcessTools to 
exec the child is penalized by adding this to its test description:

   31  * @build jdk.test.lib.Utils
   32  *        jdk.test.lib.Asserts
   33  *        jdk.test.lib.JDKToolFinder
   34  *        jdk.test.lib.JDKToolLauncher
   35  *        jdk.test.lib.Platform
   36  *        jdk.test.lib.process.*

Can we get a bug submitted to cull most of this? A lot of our tests 
needs to launch child VMs and a simple ProcessTools with minimal 
dependences would be preferred.
