We should be able to use the test results from testcase: http://129.148.174.102:8000/dennis/bug/dolphin/6.0update/6357710/unitTest.html (deployment test JDK-6357710). But I am not able to locate the results for jdk 8 in aurora. Written to dennis/jitender for pointers

EVALUATION This is a regression of CR 6357710. Need a fix in both deploy and JDK code. Deploy team also filled a CR (7060523) for the issue. SQE has approved to defer CR 7060523 for JDK7. Note that this should be a partial fix for bug 7060523, which will only apply to JDK repository. Deploy code will address the issue in CR 7060523 separately. The problem in applet exists since 6u23, not a showstopper for 7. The problem will only happen when the applet request TLS handshaking/renegotiation very frequently. No wide scope impact. No impact on normal JSSE/HTTPS applications except the Java plugin. The issue in JSSE has been there since the SSLSocketImpl.java was created.
