Sometimes the compiler stops throwing an java.lang.NegativeArraySizeException. This is not deterministic and changing some arbitrary code can solve this problem until it reappears suddenly.

It is may be related to this issue

Disable the optimization with

      scalacOptions in Compile ++= Seq(
        "-Ynooptimise"
      )

seems to solve it. But that is no solution of course.

This is the trace:

java.lang.NegativeArraySizeException

Please compile with -Ydebug -Ylog:jvm to see what method is triggering the problem: https://github.com/scala/scala/blob/2.11.x/src/compiler/scala/tools/nsc/backend/jvm/GenASM.scala#L1394

We'd need to see a standalone example to be able to fix this (or to confirm that its a known bug)

@retronym said:
Another useful diagnostic would be to identify the minimal set of optimizer flags that is needed to trigger the problem:

⚡ scala -optimize
Welcome to Scala 2.11.8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_71).
Type in expressions for evaluation. Or try :help.

scala> :settings
-Yclosure-elim = true
-Yconst-opt = true
-Ydead-code = true
-Yinline = true
-Yinline-handlers = true
-d = .
-encoding = UTF-8
-nowarn = false
-optimise = true

ie. does it show up with scalac -Yinline, or scalac -Ydead-code, etc.

Jens Kleemann (jens-0) said:
The inline optimization causes the exception. Using

scalacOptions in Compile ++= Seq(
        "-Ynooptimise",
        "-Yclosure-elim",
        "-Yconst-opt",
        "-Ydead-code",
        //"-Yinline", // TODO: Causes NegativeArraySizeException in Build
        "-Yinline-handlers"
       )

it compiles fine.

There is following debug output:

With -Ydebug and Ylog:jvm you can see this exception:

@retronym said (edited on May 19, 2016 11:26:09 AM UTC):
One thing you could try would be to replace:

package object foo { implicit class RichActorRef(...) }

with

package foo
class RichActorRef

package object foo { 
  implicit def enrichActorRef(): RichActorRef = ...
}

I suspect that will get rid of the duplicate symbol exceptions at the end of your last comment. Not sure if we've got an open bug for that or not, but all the associated code has been rewritten in the new backend in 2.12, so that problem will be gone.
