Hi,

It's great to see some support for kawa in slime.. I wanted to give it a go today but ran in a few showstoppers. With the latest kawa compiler I ran into an error which might be a compiler bug, when issuing the compile command: (compile-file "swank-kawa.scm" "swank-kawa") I get a stack trace:

java.lang.Error: popType called with empty stack swank$Mnkawa.dispatchEvents(java.net.Socket)java.lang.Object at gnu.bytecode.CodeAttr.popType(CodeAttr.java:321) at

After going back a few versions (to revision 6150) the swank-kawa compiles but I get the following error when starting slime in emacs:

Any ideas how to fix these? (Running on OS X Leopard, Java 1.6.0_07) Thanks in advance
