[p2-dev] How to tell that unpacked jar is good?

[Henrich Kraemer <henrich.kraemer@xxxxxxxxxx>]

Bug http://bugs.sun.com/view_bug.do?bug_id=6313847 'pack200/unpack200 creates corrupt class file' appears to be a case where unpack did not seem to fail, but problems at runtime occured.
The workaround seems to be to use effort 4 when creating the jar.

It appears that one cannot determine programmatically whether an unpacked jar is corrupt or is there a way?

Thanks,

Henrich
