[abc] Jasmin error

Hi.

When trying to weave jar to jar with abc, I get a bunch of Jasmin errors
as the following.
First I thought, it might be the case because I was using Java 5
bytecode. But then I tried "retroweaver" to have it converted to Java
1.4. code and still I get the same errors. What may I be doing wrong?

Cheers,
Eric
