Exception handler not found

[Sami Tikka]

I have this short Java program that I've built that doesn't work with
Kaffe but does with JDK. The program is supposed to get an URL from the
command line, get the contents of the URL and write it to stdout.
A useful little tool. Here's what happens:

melkor lib$ CLASSPATH=HttpGet.jar
melkor lib$ export CLASSPATH
melkor lib$ kaffe fi.iki.sti.util.Http get
http://hollywood.research.nokia.com/
sp out of range: 2 <8> 7
Kaffe: code-analyse.c:1887: mergeFrame: Assertion `to != 0' failed.
Aborted (core dumped)
melkor lib$

I used kaffe-snap.tar.gz from www.transvirtual.com which I downloaded
and compiled today on Linux 2.1.118.

I've attached the files and a jar file of the classes I used to invoke
the above test.
I hope this helps you to fix kaffe. I really enjoyed using the 0.1.0
version of kaffe to learn Java programming.
