Code Review Request 8141593 Test RetryHttps timed out intermittently

[Xuelei Fan]

Hi Weijun,

Are you available review this patch for JDK-8141593?

    http://cr.openjdk.java.net/~xuelei/8141593/webrev.00/

Test RetryHttps.java timed out intermittently, and the exception looks
weird to me:

   javax.net.ssl.SSLException: Unsupported or unrecognized SSL message

Looks like there is something wrong of the underlying SSL/TLS
handshaking.  But I'm not sure of the root cause yet.  As this issue
happens intermittently, I cannot reproduce it and make further evaluation.

This is not a fix actually. I just enable the JSSE debug in the test.
Hope next failure, the debug log can be helpful.

Thanks,
Xuelei
