Hi all,

could you please review this tiny fix for compiler/ciReplay/ tests? these tests try to crash JVM by running '-Xcomp -XX:CICrashAt=1 -version', but if they are run w/ AOT'ed java.base, there is nothing else to compile in '-version', so JVM doesn't crash and the tests fail. the fix replaces usage of -version w/ a class w/ empty main method, so crashes will happen w/ or w/o AOT'ed java.base.

JBS: https://bugs.openjdk.java.net/browse/JDK-8150757
testing: compiler/ciReplay/ tests w/ and w/o AOT'ed java.base

Thanks,
-- Igor
