The code change is OK. However I wonder how are you running the tests concurrently? Are you talking about running tests from different JDKs, or just parallelizing one testsuite? I've been experimenting with that (using JTReg concurrency setting) some while ago, and while I managed to get some tests running fine in parallel, I remember that it would be quite difficult for others and there was no option to annotate them to run non-concurrently.
