On some Windows machines we see sometimes OOM errors because of high resource (memory/swap) consumption. This is especially seen when the jtreg runs have higher concurrency. A solution is to put the java/lang/StringBuilder tests in the exclusiveAccess.dirs group so that they are not executed concurrently, which helps to mitigate the resource shortages. Of course this has the downside that on very large machines the concurrent execution is not done any more.
