"generate code" hangs eclipse.

I increased the java memory to 1GB, but this did not help, and I did not see java use any more memory than when it was 512.

Eclipse hangs if you open the generate code dialogue (by right clicking on a "soap ui webservice"), then simply hit the close button.

It does it 100% of the time.

If it helps, here is the wsdl:
