Hi,

Please review the fix for JDK-8141651:

    http://cr.openjdk.java.net/~xuelei/8141651/webrev.00/

In JDK 9, there is a deadlock introduced.  One thread can lock
SSLSocketImpl instance, and try to lock SSLSocketImpl.writeLock; Another
thread may lock SSLSocketImpl.writeLock, and then try to lock
SSLSocketImpl instance.  A deadlock happens.

This fix is trying to remove the latter lock sequence.

No new regression test as it is hard to re-produce the issue.

Thanks,
Xuelei
