Why are the following listed in the @build tags:

   jdk.test.lib.Asserts
   jdk.test.lib.JDKToolFinder
   jdk.test.lib.JDKToolLauncher
   jdk.test.lib.Platform
   jdk.test.lib.process.*

None of these are interesting to these tests. There was a lengthy thread 
last year (I think started by JDK-8180805) where the issues of implicit 
compilation were discussed. I thought that jtreg was changed to compile 
test library classes in their own directory so that test infrastructure 
classes that relied on implicit compilation could work without the 
interim NoClassDefFoundError that we used to hit when running tests 
concurrently and where tests didn't precisely list every test library class.
