One of the guys in my office had a problem with Java2WSDL failing with this
exception:

The offending line of code is:
cache.put(cls, cachedInfo);
cachedInfo may be null if something went wrong while calling javap, and you
can't put a null value in a Hashtable. The code should be using a HashMap
instead of a Hashtable (and probably ArrayLists instead of Vectors). Here's
the diff for the fix:
