I think it's good idea to separate java launcher and tools. Here is the 
new JdkFinder: 
http://cr.openjdk.java.net/~ykantser/8007142/webrev.02/test/lib/testlibrary/jdk/testlibrary/JdkFinder.java.html. 
It now possible to retrieve java/tools both from the test.jdk and 
compile.jdk.

JDKToolFinder.getJDKTool("java") became JdkFinder.getJavaLauncher  in 
the createJavaProcessBuilder 
(http://cr.openjdk.java.net/~ykantser/8007142/webrev.02/test/lib/testlibrary/jdk/testlibrary/ProcessTools.java.html).
