OutOfMemory while throwing OutOfMemory while ...

[Enno Rehling]

Hello,

Funny thing happened while trying to port kaffe: I ran out of memory while
in jthread_init, and kaffe tried throwing an OutOfMemory Exception. If I see
it correctly, in order to do that, it has to allocate a buffer for the
"java/lang/OutOfMemoryError" String. Which, having run out of memory,
failed, resulting in -- you guessed it -- another attempt to throw an
exception.

I'm wondering if this is "normal behaviour" of kaffe or whether I mucked up
something (I've meddled with my kaffe for so long that I can't really say
anymore).

Oh, the original version was taken from the cvs on August 27th.
