Hi all,

could you please review this small and trivial cleanup in TEST.ROOT files of test/jdk/ and test/hotspot/jtreg test suites?
from JBS:
> to make sure that classes listed in `requires.extraPropDefns.bootlibs` are in BCP, jtreg automatically adds corresponding `-Xbootclasspath/a:` to the options list, so `requires.extraPropDefns.vmOpts` doesn't have to have `-Xbootclasspath/a:bootClasses`
the patch 
 - removes -Xbootclasspath/a:bootClasses from requires.extraPropDefns.vmOpts
 - moves jdk.test.lib.Platform and Container classes from requires.extraPropDefns.bootlibs to requires.extraPropDefns.libs as there is no need for them to be in BCP

JBS: https://bugs.openjdk.java.net/browse/JDK-8245874
testing: tier1
webrev: http://cr.openjdk.java.net/~iignatyev//8245874/webrev.00

Thanks,
-- Igor
