Sounds like you're getting a StackOverflowError on initialization of
System properties, and then wrongly pass the exception to the native
method instead of new Properties object.
See libraries/javalib/java/lang/System.java in the static initializer
section. Take a look at FAQ.debugging, fire up gdb and try to figure out
why the StackOverflowError doesn't propagate out of the static
initializer, but overwrites the object reference instead. If it turns
out to be a bug in kaffe we haven't found yet, please send in a patch.
Last but not least: best of luck!
