RFR: Disable all DES cipher suites

NoDesRC4CiphSuite.java
----------------------
Please move line 30-31 out of the test comment block. The two lines
will be parsed as part of the run parameters.
I would prefer to use othervm mode. Otherwise, once there is a test
case does not run with othervm and changes the context, this test may be
not reliable any more. If this test failed, it is hard to evaluate the
root cause if it is impacted by other test case.
I may prefer to use System.err for new test case as the SunJSSE default
debug log now is dumped to System.err. Dumps on System.out and
System.err are not synchronized. Using the same stream may make the
debug log easier to read.
Thanks,
Xuelei
