infinite recursion, SIGSEGV thrown and caught over and over, might be reflection related

Oops, I actually have another clue to add.
node/State.java:
 try {
 recv = this.getClass().getDeclaredMethod(
 "receivedMessage", new Class[] { Freenet.node.Node.class,
 mo.getClass() } );
 }
 catch (SecurityException e) {
 throw new BadStateException("??? SecurityException ??? WTF!!: "+e);
 }
 catch (NoSuchMethodException e) {
 throw new BadStateException("State does not receive this message: "+e);
 }
 
 if (!State.class.isAssignableFrom(recv.getReturnType())) {
 throw new BadStateException("bad receivedMessage() return type declared: "
 + recv.getReturnType());
 }
 
 Class[] exceptions = recv.getExceptionTypes();
 for (int i=0; i<exceptions.length; ++i) {
 if (!StateException.class.isAssignableFrom(exceptions[i]))
 throw new BadStateException("bad receivedMessage() exception declared: "
 + exceptions[i]);
 }
When this is run with the gij interpreter, I see this exception:
Freenet.node.BadStateException: bad receivedMessage() exception declared: float

...which seems interesting.
