with latest 2.12.1 nightly, "class scala.IndexOutOfBoundsException not found"

[SethTisue]

this was found by the Scala 2.12 community build, but can be reproduced independently, on the 2.12.0 branch of paradise, with:

++2.12.1-de003f7-nightly
set every scalaBinaryVersion := "2.12"
tests/test

resulting in a lot of repeated errors like:

[error] /Users/tisue/paradise/tests/src/test/scala/annotations/run/KaseIdentityObject.scala:54: exception during macro expansion:

@xeno-by are you available to look at this? if this is an issue for Scala 2.12.1, we'll need to know soon. also, this is making every 2.12.x Scala community build fail.

[xeno-by]

I will do that tomorrow. Been travelling the last week.

@SethTisue @adriaanm What resolver should I use?

What resolver should I use?

resolvers += "release-temp" at "https://scala-ci.typesafe.com/artifactory/scala-release-temp/"

I noticed I was answering this question a lot, so: http://stackoverflow.com/questions/40622878/how-do-i-tell-sbt-to-use-a-nightly-build-of-scala-2-11-or-2-12

[xeno-by]

Can reproduce. Will investigate now.

[xeno-by]

It turns out that paradise itself is fine.

It's the code of the test macro that changed behavior. After I fixed the test, everything became green again. See a976e75 for more information.

thanks Eugene! looking good over at scala/community-build#404
