Wouldn’t this be an ASM problem?

[azmras]

You are right.
I would stick to 2.0.2 for now then, wait for their fix and your next upgrade...
Thanks

I reported a similar issue to the ASM project just yesterday. If you want to debug this issue, maybe rebuild ASM with my change to SignatureReader to get a better understanding why this fails.

Otherwise, if I know where org/eclipse/persistence/indirection/IndirectMap.class is from (EclipseLink?), I could investigate myself (EclipseLink 2.7.2 from Maven Central doesn't exhibit this problem AFAICS).
