I'm not an expert on the details here.  My understanding is that there
is a special "JCR" section that lists all the classes, and that this
list is passed to _Jv_RegisterClasses when the library is loaded.

Search for JCR in gcc/crtstuff.c for the implementation.


Hmm, I looked at the stack trace more closely, and dug with strace a
bit, and things look even weirder.  Apparently we're opening two
different copies of lib-org-xml-sax.so (one in $libdir and one that is
installed elsewhere).

This shouldn't be happening.  I'll investigate more, sorry for taking
your time.
