to believe that's for the C stack, not the Java stack).
Has anyone run into this? Any ideas?
If indeed you have a recursion which legally overflows, maybe you
could re-implement your recursion to avoid that using multiple
threads. The idea is that you attempt to find the stack length using:
workerThread.getStackTrace().length,
and then see if that length is approaching the maximum stack length,
whatever value that might be. If so, you could continue the recursion
in another thread. That should not be too difficult... You would need
to test this however, because the above mentioned Thread method does
not guarantee a true result on all VMs. If it works, overflowing
should not be a problem. Just make sure your recursion actually does
end at some point :)
Can anyone see this working?
