Java can't catch native code exceptions. The exception has to be caught

Yes, that's what I meant by conversion.

in the C++ code but so far traditional exception handling isn't working. I even tried put a try/catch block around the entire function and it still crashes.

You mean you can't catch the C++ exception in C++ code? Did you try it in a small console application (just to make sure the problem is not JNI-related)? Boris

I've no idea why a C++ exception shouldn't be caught in C++ code. Did you try catch(...) to test if this works at least? Boris

Hi, I had a similar problem a few weeks ago with catching an exception from boost::threads. It had to do with symbol visibility (I am using the gcc compiler flag -fvisibility=hidden), see http://lists.boost.org/boost-users/2008/09/40268.php (problem solved/circumvented) http://lists.boost.org/boost-users/2008/09/40270.php (additional insight) I have also seen a trac ticket regarding this issue for many parts of boost, including regex: http://svn.boost.org/trac/boost/ticket/2114 Regards, Roland Matthew LaCrosse wrote:

Hi Matthew, just to be thorough: Visibility issues can also occur with MS Visual C++. It is not a "speciality" of gcc, although the command line flags might be different, of course (I wouldn't know about that). If you're compiling with visibility=hidden (or the MS equivalent), then I would expect the problem you described (not being able to catch an exception is exactly what happened to me). Not running into exceptions is also a good solution, though :-) Regards, Roland Matthew LaCrosse wrote:

Thank you Roland. I haven't tried compiling with gcc yet. I'm using MS Visual C++ 9.0.

What I ended up doing was just writing a filter to block the invalid expression that was causing the crash.
