We mistakenly use -XX:-UnlockDiagnosticVMOptions instead of
-XX:+UnlockDiagnosticVMOptions in a ADD_JVM_ARG_IF_OK call. This means
that the test will always fail and the arguments will never be added to
the command line.
Since this has been the case all time along, it's probably not that
important, but it was added to keep down the logging when using a debug
build as boot jdk, which has probably not been tested that much either.
We should either fix this or remove the arguments completely.
