While chasing 4432433, I ran into this crash when using ladybird to bootstrap:

to reproduce:
1. set ALT_BOOTDIR to /usr/local/java/jdk1.3.1/linux-i386
2. in <merlin_sdk>/make, run "make all docs".

It is reliably reproducible on my dual PIII-866 with Redhat 6.2 SMP kernel
just a few minutes into make. And when it crashes, it seems to crash while
executing java -cp ../../../tools/javac/jstyle.jar jstyle.JSFormatter -fs -ll80.

I did not see crashes when using 1.3 or 1.4 in ALT_BOOTDIR nor building on
Solaris with 1.3.1.

Another run shows slightly different stack trace (but essentially the same):
