Mozilla crashing when viewing java console

I installed the Java 1.4.2_19 JRE, SDK, and Mozilla plugin in SCO (OpenServer 5.0.7). However, every time I try and view the java console, the browser immediately closes. Likewise, if I navigate to a website that tries to load an applet, the browser immediately closes.

I've checked and verified that the java plugin in /usr/lib/mozilla/plugin is correctly linked to /usr/java/...etc

Does Mozilla store log files anywhere that might shed some light on what's going on? I checked the admin system log viewer tool, but it didn't have anything relevant.

Is 1.4 new enough for that Mozilla? I think of this as a 1.6 fading to 1.7 era.

You can run it in strace/truss/tusc and see what it is dying of, usually in stunning detail. You can attach it with -p just before hitting enter to visit an applet or whatever.
