[izpack-devel] Problems with VM 1.5

here is some new information on this topic. Unfortunately it is rather

First of all, I see the problem now as well. But only with version 3.8. This
supports me in my believe that the problem is not with the JVM or with the
shortcut DLL per se. Years ago I had some problems of this type but it was
with plain vanilla Java code. While this proves nothing, at least it shows
the possibility that it does not necessarily have something to do with
native code.

The one thing that bugs me is that the problem does not show in any
consistent way. Just now I saw it two times out of 16 runs....

there is nothing attached, I suppose the mailing list strips off

The fact that it does not just crash always or never, but just sometimes it
really strange. I wonder if it might have something to do with the dead
threads hogging some resources that are exhausted after so many tries.
Perhaps a more realistic test would be to implement the test loop in a batch
file, so that the VM actually exits before you start the next test.

If all else fails we still have the option of not deleting the DLL. That's a
bit dirty and I don't really like it, which is why I spent so much time back
then to come up with a solution for this problem. Still, it is much better
than crashing and it would not be any worse than many other applications
that clog up the temp directory with their garbage (though I did not want to
be part of that crowd).

Julien, what do you think about this approach?
