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.
It will fail in the interpreter mode :(. Since this functionality depends on implementation, the test may pass here and fail there. I'd like to hear from DRLVM gurus that e.g. the test is incorrect because the stack size limit in the DRLVM is restricted to some value which cause StackOverflowError and the correct number in the test should be XXX. I know that 200 is acceptable :) but should it be larger? Elena 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.
