Elena,
You wrote: RI*: 3689 It's mean that test is failed on RI, isn't it? So 7000 isn't correct for RI. Let's change it to 3000. And test start's pass on our VM. Pavel. On 12/11/06, Elena Semukhina <[EMAIL PROTECTED]> wrote:
Pavel, what is incorrect in the test? It passes on windows on IBM VME and JRockit. As for the magic number 7000, I think the author of the test considered it quite satisfactory . In the comments to the test he wrote that an alternative java craches with 200000:). The JVM Spec reads: * If the computation in a thread requires a larger Java virtual machine stack than is permitted, the Java virtual machine throws a StackOverflowError. So throwing StackOverflowError is legal and the stack size limit depends on implementation. The question is whether the test has to pass on the current DRLVM implementation. If it fails legally, then we should fix the test so that it reflects the status quo. Thanks, Elena On 12/11/06, Pavel Afremov <[EMAIL PROTECTED]> wrote: > > I think that test is invalid.
