ArrayIndexOutOfBoundException when running mimaReport

[etorreborre]

I added the mima plugin to the specs2 4.x maintenance branch (destined to track Scala 2.x) and I got several exceptions:

specs2(specs2-4.x-maintenance)> coreJVM / mimaReportBinaryIssues
[error] stack trace is suppressed; run last coreJVM / mimaReportBinaryIssues for the full output

The branch with the mima change is accessible here.

This might be already fixed with #655. I'll try to verify.

[dwijnand]

Yeah, fixed with a local publish of #655. Before:

FYI, saw something similar on scodec-bits when upgrading to sbt-mima-plugin 1.0.0. I'll try with 1.0.1 once released.

I haven't got time today, but I've opened #664 so you and anyone can track that for the release. 🤞🏼 this week
