What is considered proper java support? GCJ?
Dave, have you tinkered with GCJ lately?
GCJ-4.4 works fine on hppa, currently waiting in NEW ... so if you do want to
see this resolved, please help with getting this accepted.
Note that this doesn't work very well with NPTL (Ubuntu karmic), so please
make
sure that this continues to work with an glibc update.
OpenJDK is non-trivial. Andrew Haley did have a look at this and came to the
conclusion that the byte code interpreter for the zero port needs porting for
archs with upward growing stacks.
It might not be horribly difficult to fix. The crash comes when the VM
calls mprotect() on the second page of the stack as a guard against stack
overflow: obviously that isn't going to work if your stack grows upwards.
I don't know if that is the only place in which the VM assumes the stack
grows downwards. It's a matter of debugging, if anyone on hppa cares enough
to get OpenJDK working.
Andrew.
