It gets a null pointer and says it can't use ASM in MVEL, thus uses
reflection mode. That's fine as reflection is the mode we put MVEL in
anyway.<br>

The information is about 800 lines long and it clearly shows classes
loading from my "minimal core Drools" plugin; when I add the entire
Drools distribution to the classpath I get a similar dump with loading
from the complete Drools distribution. I am attaching a text file with
this information but I am guessing it will get stripped away by the
server. I very much appreciate your help with this.

Mike,
I don't remember right now the exact flag to dump classpath, but adding
"-verbose:class" as a VM parameter on your launch configuration shall do the
trick. Just look for "org.objectweb.asm" package's Classes being loaded and
you will know where they are being loaded from. You will easily be able to
see if there is any other asm library clashing with the mvel required ones.

Sorry - am using Eclipse in OSX and have no clue how to ask it to dump its
classpath.I can print out the .classpath file but this is clearly not
really relevant.
Mike,
This looks like a classpath problem indeed. Did you tried asking the JVM
to dump its classpath so that you can know for sure what jars are included
and if any of them embeds a non-compatible ASM version ?
