Hi,
I am getting the following error trying to extend java.lang.Exception
in the latest revision of Clojure:
user=>(defmacro defexception [name]
`(try
(gen-and-load-class (quote ~name) :extends Exception)
(catch java.lang.LinkageError le#
(. le# (printStackTrace)))))
user=> (defexception my.Exception)
java.lang.ClassFormatError: JVMCFRE114 field name is invalid;
class=my/Exception, offset=0

The 'defexception macro is actually from swank-clojure. I have used
this successfully in the past, the difference here is that I am using
the IBM 1.6.0 JRE in this case:
[EMAIL PROTECTED] trunk]$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build pxi3260sr2-20080818_01(SR2))
IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 Linux x86-32
jvmxi3260-20080816_22093 (JIT enabled, AOT enabled)
J9VM - 20080816_022093_lHdSMr
JIT - r9_20080721_1330ifx2
GC - 20080724_AA)
JCL - 20080808_02
I'm not sure if this is Clojure's bug or IBM's. I don't have the
luxury of testing this on any other JVMs at the moment. I presume that
since everyone is able to use swank-clojure at the latest revision
that this is not happening on other JVMs?
