I found this old thread suggesting that the JDK code may not be correct and
asking whether someone saw this assertion trip in the wild:
http://osdir.com/ml/core-libs-dev/2014-11/msg00337.html so this might be a JDK
bug rather than a Groovy bug. However we didn't see this assertion error before
we upgraded, so maybe there is a related Groovy change that made it more likely
to happen? Like the email thread mentions, one reason why few people hit this
assertion error might be that few people run with system assertions (-esa).
We have only seen this assertion trip on a JDK 7 (not 8) but I couldn't find
any information related to fixing WildcardTypeImpl between JDK7 and JDK8, so
I'm not totally sure the problem is fixed if running with JDK 8. It might just
be rarer.
If you have confidence this is a JDK bug and not a Groovy bug, please feel free
to close it. Hopefully this will at least serve for future reference if anyone
else hits the same issue.
