NullPointer when generating Class to Repository from Java round trip


Visual Paradigm UML 6.0 build 20061209) (Part of VP Suite 3.0)

I have made Java round-trip from source code and started adding classes individually to Class Repository. I can generate 10 classes to repertory, but after that it stops working. (right click -> revers ‘my class’ -> class repository) I have restarted program several times.

Here’s some log information:

I upgraded to lates VP Suite 3.0 SP2 version and now it has another problem. Java round-trip does not know how to handle class level instance blocks. It crashes all the time when generating class to repository. I will send you information requested.

Can you send us the complete vp.log file to have a look? You can find it inside the bin folder of VP’s installation directory. Thanks!
