> test.classes points to the directory w/ classes from a test, but not from test libraries. directories w/ all needed classes (either from a test or from libraries) are added to classpath and 'test.class.path'. ClassFileInstaller uses class loader to get resources, test.Empty will be in CP, so ClassFileInstaller will have access to it.

Sorry still don't understand the change. Where does:

@build test.Empty

place Empty.class? If not in test.classes then how has this test ever 
passed? I'm assuming the change is needed because it no longer passes 
with the updated jtreg.
