                  I think I would prefer this as a separate change. I'm
                  not very good with TEST.groups, but it looks like your
                  suggested changes are correct. However, I would prefer
                  the get more attention to that change and thus it
                  would be better to send it out as a separate review.<br>

                      <br>
                      What do you think about always making

                      check for the uniprocessor case (as opposed to

                      check it)?  <br>
                      <br>
                      ForceDynamicNumberOfGCThreads is a diagnostic flag<br>
                      <br>
                        diagnostic(bool, ForceDynamicNumberOfGCThreads,
                      false,                    \<br>
                                "Force dynamic selection of the number

Summary:

Part 1 is a test bug that tries to run G1 on embedded SE builds. Not changed by this webrev.

Part two is assertion failure that is being fixed by this webrev.

This is a fix for bug that triggered an assert when running CMS on very 
small machines - 1 core x86, or 1-4 core ARM. This may seem unlikely but
 can easily happen when running virtual instances.

Failure stack traces also show bug crashing printing a stack trace, but this is being tracked in another bug.

Thanks,

- Derek
