Hi Gilles,
isn't it possible to pass all exceptions from the Java interface
to the calling method? I can live with the current handling of
exceptions as well, although some exceptions can be handled
within my program and some will break my program even if I want
to handle exceptions myself. I understood PR 1698 in the way, that
all exceptions can be processed in the user program if the user
chooses MPI.ERRORS_RETURN (otherwise this change request wouldn't
have been necessary). Nevertheless, if you decide, things are as
they are, I'm happy with your decision as well.
Kind regards
Siegmar

Siegmar and all,
i am puzzled with this error.
on one hand, it is caused by an invalid buffer
(e.g. buffer size is 1, but user suggests size is 2)
so i am fine with current behavior (e.g.
java.lang.ArrayIndexOutOfBoundsException is thrown)
/* if that was a C program, it would very likely SIGSEGV, e.g. Open MPI does
not catch this kind of error when checking params */
on the other hand, Open MPI could be enhanced to check the buffer size, and
throw a MPIException in this case.
as far as i am concerned, this is a feature request and not a bug.
thoughts anyone ?
Cheers,
Gilles

Hi,
I have installed v1.10.3-31-g35ba6a1, openmpi-v2.0.0-233-gb5f0a4f,
and openmpi-dev-4691-g277c319 on my "SUSE Linux Enterprise Server
12 (x86_64)" with Sun C 5.14 beta and gcc-6.1.0. In May I had
reported a problem with Java execeptions (PR 1698) which had
been solved in June (PR 1803).

Unfortunately the problem still exists or exists once more
in all three branches.
