Issue1195

While trying to import zope.interface 3.3.0 or 3.5.0 into Jython trunk 
(r5721), it blows up with an error. See attached textfile for the full 
traceback. We encountered this issue while trying to make Twisted run on 
Jython (zope.interface is it's only required dependency).

Sorry guys, this was a bad build on my side, after 'ant clean', 'ant' it 
worked, feel free to close the ticket. Some other random info; we tried 
pyOpenSSL with Jython but got an expected error that can't be worked 
around I guess..

error: Compiling extensions is not supported on Jython

No worries, I knew it was an ant clean issue as soon as I looked at the 
log

We obviously don't support C extensions, so that error is expected. If 
pyOpenSSL has a pure python fallback module for its C modules, I can 
point you to some other projects' setup.pys that will fail gracefully on 
Jython and instead use their pure python fallbacks.

But last time I checked pyOpenSSL required the C stuff. So it just plain 
won't work on Jython
