Re: Problem with asm-tree :org/objectweb/asm/tree/MethodNode

hi,

I had a similiar problem and I solved it by using

           <dependency>
               <groupId>org.ow2.asm</groupId>
               <artifactId>asm-debug-all</artifactId>
               <version>5.0</version>
           </dependency>

However, I don't know the difference between the "all" and the 
"debug-all" version.

Cheers,
Alex
