Comments
EVALUATION There are a couple of problems here. - The test in question doesn't scale to 64-bit machines. It assumes that an attempt to specify a value of 42g to the -XX:MaxDirectMemorySize flag will be ignored. This is true on 32-bit machines, since 42g parses to a negative number, which is then ignored by sun.misc.VM.maxDirectMemory(), but it's not true on 64-bit machines. - The VM.maxDirectMemory method doesn't behave properly on negative numbers. Rather than taking the hardwired default of 64MB it should instead take the value of Runtime.getRuntime().maxMemory(). This difference is more noticeable now that we have ergonomic GC sizing. I've submitted a separate bug for the second problem (5047688). The equivalent test in the J2SE regression suite also fails on 64-bit machines. We will fix that test (4862640), but it'll up to CTE to apply the corresponding fix to their copy of it. (It would probably make more sense for that test simply to be deleted from the CTE suite since it's redundant.) -- ###@###.### 2004/5/14
