The following test failed due to an exception on Solaris-X64
in the slowdebug config using jdk11+25 bits:

javax/management/remote/mandatory/connection/FailedConnectionTest.java

The test only failed in 1 of 3 'slowdebug' bits runs so I'm
tagging this bug as intermittent. It did not fail at all in the
'fastdebug' or 'release' bits runs.

Here is a snippet from the log file:
