You are right about the ... sym->st_value + ooff ... is supposed to call the atexit function. It might be interesting to add a

DL_DEB(("%x\n", sym->st_value + ooff);
after that line, and then attempt to find which object the symbol was found in. Perhaps the java library provides it's own atexit() routine.

For debugging purposes, you could try to move the 'Finally make' block, all the way thru the 'if (map_link) { ... } ' code above the 'Schedule a routine to be run at shutdown'

That way gdb may be able to be more useful when it crashes.

If you send me instructions on what to fetch and how to build this, I can help debugging this more.
