Description

This is no really so much a bug in Groovy as a note that ASM changed their API in 1.5, but for reasons that Groovy may be very interested in. See...
http://www.objectweb.org/wws/arc/asm/2004-08/msg00022.html

Basically, the new version of ClassVisitor added an "int version" parameter to the visit() method so that the bytcode version would not be hardcoded. This is probably important with JDK1.5 getting closer to release. Go here to see the change...
http://cvs.forge.objectweb.org/cgi-bin/viewcvs.cgi/asm/src/org/objectweb/asm/ClassVisitor.java

Might want to just bite the bullet and upgrade to asm-1.5 because if one attempts to use asm-1.5 with the latest Groovy built from CVS, one gets...
