Hi,
I successfully installed openmpi-1.8.5 on my machines (Solaris 10
Sparc, Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with
gcc-4.9.2 and Sun C 5.13. Unfortunately I get an error for my Java
programs for both versions if I use two Solaris machines. It works
fine for two Linux machines. "mpijavac" compiles the program without
warnings or errors.
I get the following error if I use two different Solaris 10 x86_64
machines.

I would be grateful if somebody can fix the problem. Thank you very
much for any help in advance.
