Hi all,

could you please review this patch?
from JBS:
> as of now, nsk.share.GoldChecker reads golden files from the current directory, which makes it necessary to copy golden files from ${test.src} before the execution of the tests which use GoldChecker.

after this patch, FileInstaller actions will become redundant in 103 of :vmTestbase_vm_compiler tests and will be removed by 8251127.

Thanks,
