closed/javax/management/remote/mandatory/sslStub/SslStubTest.sh times out in JDK8-B22

I observed the following SDK/JDK test fail in my baseline test for JDK8-B22
on Solaris-X86 and Solaris X64:

    closed/javax/management/remote/mandatory/sslStub/SslStubTest.sh

Normally, timeouts don't catch my attention, but the same test on
two different configurations in the same baseline build? Definitely
unusual. Also, if a test times out because a machine is overloaded,
then all phases of the JavaTest/JTREG infrastructure for the test
are typically also slow.

Here is the config ID and elapsed times from the Solaris X86 config:

Here is where the test timed out:

I only included the output for the last two tests above. This
run failed on the 7th test.



For the Solaris X64 config:

java version "1.8.0-ea"
Java(TM) SE Runtime Environment (build 1.8.0-ea-b22)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b10-fastdebug, compiled mode)

The elapsed times were similar:

elapsed time (seconds): 0.0
elapsed time (seconds): 1.888
elapsed time (seconds): 1.887
elapsed time (seconds): 300.007


And the test timed out in the 6th test:
