Hi Alan,Please review the fix to bug 7185340. The webrev can be found at, http://cr.openjdk.java.net/~dxu/7185340/webrev.01/.
The fix is to increase the -XX:MaxDirectMemorySize parameter from 64M to 75M. Bug 7176485 allows the temporary buffer cache to grow to IOV MAX. Therefore, in Windows each thread can have up to 16 direct buffers in the cache, which causes the addition of this jvm parameter to run this testcase.
Thanks, -Dan
