Scala 2.12.12 ArrayOps#++ no longer able to build GraalVM native image

This was reported originally as https://github.com/sbt/sbt/issues/5756 ## reproduction steps using Scala 2.12.12: ```scala val s = "foo" val xs = s.getBytes("UTF-8") ++ System.lineSeparator.getBytes("UTF-8") ``` (actual code looks like https://github.com/sbt/sbt/blob/8ce423b088b85bb3016cfb994791c3536f7b627e/internal/util-logging/src/main/scala/sbt/internal/util/Terminal.scala#L384-L391) Then...

This is a feature proposal Currently we have [TextFileOutput](https://github.com/scala/pickling/blob/v0.10.0_2.10/core/src/main/scala/pickling/FileOutput.scala) but it has some potential issues. 1. [PrintWriter](http://docs.oracle.com/javase/7/docs/api/java/io/PrintWriter.html) eats exceptions ("never throw I/O exceptions") so it's probably not recommended for anything...

GraalVM native image test
