When I compile jar into shared library all symbols become local when
-findirect-dispatch is specified. Local symbols can't be found by dlsym.
-findirect-dispatch options shouldn't change symbols from global to local since
external callers may choose to import them regardless of this option.

------- Comment #1 from aph at gcc dot gnu dot org 2009-10-19 08:55 -------
This is a deliberate design decision.
If you really need to refer to classes with dlsym, use -fno-indirect-classes.
However, this has a number of restrictions: in particular it fixes the ABI
to the specific libgcj that was used at compile time, thus requiring
recompilation every time libgcj is updated.
