Something replaced all "/" by ".".

This appears to be GNU JVM which does not understand -jar and other typical JVM
option.  This can be easily fixed however my understanding is that GNU JVM
cannot handle complicated Java2D apps like jumpshot, so you better configure
mpich2 to use either OpenJDK, Sun's or IBM's JDK.  BTW, what linux distro
you are using ?

Yes.

It is still there, see the output of
"<mpich2-untar-dir>/src/mpe2/src/slog2sdk/configure --help".
with double dashes, i.e. --with-java.
