Hi all,

could you please review this trivial cleanup in tests?
from JBS:
> ClassFileInstaller is a test utility class which copies class files to the current directory, there is no point in running it w/ external flags, hence it should be run in a driver mode.

testing: updated tests
webrev: http://cr.openjdk.java.net/~iignatyev//8244066/webrev.00
JBS: https://bugs.openjdk.java.net/browse/JDK-8244066

Thanks,
