Andreas Vajda commented on PYLUCENE-55:
---------------------------------------
I think you should be using --use_full_names to preserve the java package
hierarchy as this is a sizable tree of java classes being looked at. Otherwise
the entire namespace tree is flattened and there could be clashes (but I didn't
find multiple BabelSynset classes...)
This flag is off by default (arguably a bad default) and is documented here:
https://svn.apache.org/viewvc/lucene/pylucene/trunk/jcc/jcc3/__main__.py?view=markup
Without making any changes to JCC, I was able to build your wrappers and found
that BabelSynset does have its getLemmas() method.
I included my Makefile below, I also used --shared mode, which is recommended
(but not required).

> Key: PYLUCENE-55
> URL: https://issues.apache.org/jira/browse/PYLUCENE-55
> Project: PyLucene
> Issue Type: Bug
> Reporter: Andrea Sterbini
> Priority: Major
>
> I am trying to wrap the BabelNet API code.
> The resulting module is non-deterministically not-working (once every 5 I get
> it OK).
> This seems to be related to the order the classes are handled, because they
> are kept in a set, which has nondeterministic order.
> By changing cpp.py at line 696 to sort the class names I get a working module.
> {code:java}
> // changed from
> for cls in todo:
> {code}
> {code:java}
> // to
> for cls in sorted(todo, key=lambda c: c.getName()):{code}
> I have been luky with this way to order the classes. Possibly a better
> algorithm exists to fix this bug.
