I see you've changed the package to jdk.testlibrary - thanks for doing that.

On JDKToolFinder and finding the path to jcmd or other tools used by the 
test then it really depends what you are testing. What you have is fine 
when testing a JDK but it's not going to work when testing a JRE 
(runtime only, no tools). When testing a runtime then jtreg needs to 
invoked the -jdk and -compilejdk options (the latter being the JDK to 
use to compile the tests).  So I think the right answer for 
JDKToolFinder is to use "compile.jdk". That will work when testing a JDK 
too as "compile.jdk" and "test.jdk" are set to the same value for that case.
