using Smack API with GNU Classpath

Hello everyone,

I'm a Java Developer and I'm working mainly with embedded devices. Now 
I'm running JamVM with GNU Classpath on an ARM processor. This is all 
working fine, and I didn't had any big problems until now... I'll try to 
explain my problem as good as possible, but if someone needs some more 
information, you can contact me ofcourse!

So, I'm using the Smack API to get an XMPPConnection with my XMPPServer. 
This is working, but my CPU is running at 100%! I do have the same 
problem (CPU at 100%) when I try to run this java program on my desktop 
computer with JamVM and GNU Classpath. When I run it using Sun's JVM, 
the CPU load is around 0-1 %.

I don't have any clue what this problem could be causing, I'm trying to 
find out what part of the Smack API is causing the problems, but at the 
moment I log-in to the server, the CPU jumps to 100%... Could this be 
caused by some encryption that's been used by Smack? Since the Smack API 
needs a KeyStoreType, I'm using the gkr type since that's the one 
supported by GNU Classpath...

If anyone had this kind of problems before with GNU Classpath, or could 
solve my problem, this would be great!! Any help would be welcome since 
I'm quite stuck with this...

Kind regards,
Jan
