correct.

This bug is introduce by me in https://bugs.openjdk.org/browse/JDK-8317228 where I added support to `@require` on `-X` flags. If someone is running a test case and manually adds multiple JAVA_OPTIONS of the same type: `-Xlog:async -Xlog:gc=debug:file=gc.log -Xlog:safepoint=trace` It would crash.
