Nightly failure

Hi Jesper,

I assume that you are talking about nsk/regression/b4212983.

In that case I agree that the test is bad. It will not detect if we 
start allowing -Xmx0m since it only checks the error message for the 
initial heap size.

It is probably too late by now, but I would suggest filing a bug that 
matches the test failure to make this a know failure. The bug should be 
on hotspot/test and say that this test needs to be split up into two 
test cases. One for -Xms0m and -Xmx0m.

If you do that I think you can push hotspot-gc to main. But maybe we 
have already missed the snapshot deadline?

Bengt
