The problem here is that the Java VM is restricted by parameters to
the maximum amount of heap memory that will be allocated. It cannot
use the full installed memory unless the memory parameters are set
high enough. The Mac defaults are WOEFULLY inadequate (IIRC, I think
they are normally set at 64 MB). You will need to set the "mx"
switch (max heap size) to something more reasonable in order to avoid
sluggish performance or out of memory errors. I forget exactly how
to do this with the jnlp files, though.
Another, more obscure, possibility is that it has to do with a
problem with the hardware graphics acceleration. That affects
certain of the G4 models. In my experience with a G4 TiBook, it even
affects systems that Apple claims don't have a problem. The symptom
is claiming to run out of memory, typically when scaling a map. The
solution is to turn off hardware acceleration. There is some
information I found a while ago about that issue in the osXnotes.html
file.
