Details: https://github.com/scala/scala/releases/tag/v2.12.5


#2

There is a regression in 2.12.5 when running on Java 9 and 10: https://github.com/scala/scala-dev/issues/480 . The 2.12.5 release notes were updated to mention the regression.

We’ll be releasing 2.12.6 soon to address it. In the meantime, stick with 2.12.4 if you want to use Java 9 or 10.
