[kaffe] 1.1.4 crash report: Unexpected Exception

[Steven Augart]

I got the following error while using Kaffe 1.1.4 to build part of 
Jikes RVM:

> Internal error: caught an unexpected exception.
> Please check your CLASSPATH and your installation.
> java/lang/NullPointerException
>         at java.lang.Thread.finish(Thread.java:183)
> Abortito (core dumped)

I invoked Kaffe as:

>  kaffe -Xmx200M -classpath .:/home/augart/JikesRVM/OSS/Images.Sun/BaseBaseCopyMS/RVM.classes:/home/augart/JikesRVM/OSS/Images.Sun/BaseBaseCopyMS/RVM.classes/rvmrt.jar GenerateInterfaceDeclarations -ia 0x43000000 -out /home/augart/JikesRVM/OSS/Images.Sun/BaseBaseCopyMS/RVM.scratch/InterfaceDeclarations.h.kaffe

I should add that the Sun JDK (Blackdown 1.4.1-01) dies on this too. 
Sun throws an exception, but can't display a backtrace, to display the 
backtrace, so Kaffe isn't alone in choking on this.  All that the Sun 
JVM says is:

> Exception in thread "main" java.lang.StackOverflowError

This time around, Robilad, I haven't touched the state since the crash 
happened, so maybe this bug report will actually be useful.

I'll go onto the #kaffe IRC group at about 16:10 UTC today (11:10 am, 
USA Eastern Time) and if someone wants to walk me through what I 
should do to provide more useful information, I'll be glad to spend an 
hour doing what I can.
