I've seen this test fail on at least two occasions on linux-x86 with jdk7-b145. The tests are run with -agentvm and so are running tests sequentially in the same VM (to avoid starting a VM per test). It's possible that there are threads from previous tests or longer GC times due to garabge from previous tests that may be an influence here.
