Code review request, 8037557 test SessionCacheSizeTests.java timeout

[Xuelei Fan]

Hi,

Please review this test case update:
    http://cr.openjdk.java.net/~xuelei/8037557/webrev.00/

This is a test timeout issue.  Cause is still unknown.  I guess that one
or more of the server threads had not yet been scheduled to run by the
system within the timeout of the testing.  I added more timeout in the
code.  Hope next time timeout failure, we can get more information.

Thanks,
Xuelei
