RFR 8145919: sun/management/jmxremote/bootstrap/RmiSslBootstrapTest failed with Connection failed for no credentials (Round 2)

[Jaroslav Bachorik]

Please, review the following test change

Issue : https://bugs.openjdk.java.net/browse/JDK-8145919
Webrev: http://cr.openjdk.java.net/~jbachorik/8145919/webrev.02

The previous attempt to fix this problem was focused on the fact that 
the test tend to fail on ARM64 platforms. This is no more true, the 
failure is reproducible on various platforms if using fastdebug build.

It turns out that the test is setting up SSL in a way that only RC4 
cipher suites are to be used (the test keys are generated by this algo). 
These cipher suites, however, has been disabled (JDK-8076221).

By all means the test should be failing since the RC4 test suites were 
excluded. For some reason it started failing intermittently instead. I 
will leave the exercise of figuring out why to someone with a thorough 
expertise in SSL handshake.

The fix is straightforward - create new keys (and keystore and 
truststore) using a supported cipher suite. I opted for the default one 
(TLS_DHE_DSS_WITH_AES_128_GCM_SHA256) and update the ssl properties for 
the test to request this cipher suite. After this change the test is 
passing regularly (tried running it 200 times in a loop - without any 
failure).

Thanks,
