I see Joe's mail asking me to comment but I don't think I have much to 
add except that when running in agentvm mode + concurrency then it 
"normal" to limit the heap of the agent VMs to avoid over committing 
memory. For example, in jdk/test/Makefile then you'll see that the tests 
are run with -vmoption:-Xmx512m.

One idea would be add an @run so that they run in othervm mode. That way 
there wouldn't be any question about whether the OOME would cause side 
effects that would impact tests that run subsequently in the same 
(agent) VM. Another idea is to just check the heap size in the test so 
that it skips when the heap size is too small (this approach might be a 
faster than attempting to test and recovering from the OOME).

BTW: Just on the "@ test" then the normal way to exclude tests is to add 
the @ignore tag or else add the test to the exclude list 
(ProblemList.txt). Just mentioning it because someone might spot the 
space and wonder if it is intentional or not.
