Yes. The VerveineJ experience shows that it is complicated to extract information from the
AST.
Keep doing!

Hi again,
By looking at the stack, I think I know where the problem comes from: it seems it is
possible to have a method binding for which the declaring class is null. I thought this is
not possible, so now I would like to understand the case when this happens because I do
not know how to reproduce that.
Java is really not an easy language, and the JDT AST is also not regular enough. I only
put guard conditions when I have a case that was broken and this forces me to have a
better coverage for the future.
Of course, in the end, we will have to catch all exceptions on a file to file basis :)
Cheers,
Doru

stage of a standalone jdt2famix Java importer. This is implemented in Java, it works from
the command line and has a similar structure to VerveineJ (the previous solution relied on
JNIPort, but that did not scale well due to 32bits and needs rethinking). It is based on
FameJava and JDT, and it is available under EPL2. The model is a new Famix version
generated out of the Pharo meta-descriptions. To this end, I extended a bit the tool
support around Fame and I will follow up with some details one that.
