GWT compile is not working after upgrade.

GWT: 2.7.0
SmartGwt: 5.0p
Eclipse: Kepler
Java: 1.6

I am getting a compile error when I do a GWT Compile in Eclipse.

java.lang.IncompatibleClassChangeError: class com.google.gwt.dev.javac.asm.CollectMethodData has interface org.objectweb.asm.MethodVisitor as super class

SmartGwt includes asm-3.1.jar

I found a post on the web that says I should update the asm jar. I was wondering if anyone else has had this problem.
What did you do to fix the problem?
What version of the asm jar should I use?

thanks,
Richard
