Hard-coded timeout in a test are generally considered harmful as the test suite is run on a wide variety of systems, a single value could be too large for fast systems and too small for slow ones. The jtreg harness has an overall `-timeout:N` factor which can scale up or down all the timeouts of individual tests. I don't know offhand if there is an existing idiom to do this with junit tests from within jtreg.
