Hi I have examined your bug-report.
Debian Lenny have upgraded your openjdk installation in one of their security
updates, this new version includes of course all the security fixes and also
pused out the thumb2-jit and assembler interpreter for ARM for armel Debian
Lenny users. Unfortunately you have discovered a bug in the assembler
interpreter that triggers when running the BubbleUPnPServer.

workaround:
you can start the server with:
java -XX:+PrintCommandLineFlags -jar BubbleUPnPServer.jar

The -XX:+PrintCommandLineFlags will disable the assembler interperter and make
the code run using the c++ zero interpreter. http://gbenson.net/?p=239#comments

If possible build and try the latest Icedtea6 1.10.4 release on your ARM
server, it includes a more bug-fixed hotspot and also some alternative JVM's
like cacao and JamVM that you can use.
