What's the actual akka-actor version being used there? I've investigated
a bit and it doesn't seem to be akka-actor_2.11:2.4.10. The stackmap
frames are different I'm seeing with 2.4.10 are different than what's
show in your stack trace.
Once a colleague bumped into a similar issue with Scala and it solved it
by upgrading the JVM. Not sure what's the problem in your case.
For a bit of background. The JVM is performing some bytecode security
checks when it loads .class files — to ensure there's no possibility for
stack underflows or overflows in the generated bytecode, or that the
arguments on stack have the types expected by the method receiving them,
etc.
Before JVM 1.7 this was a thing done entirely by the JVM. After 1.7,
compilers are sometimes required to emit "proofs" that the code they
generated is behaving correctly. These proofs are the StackMapTables in
the .class files.
Apparently, your JVM verified whether the emitted proofs are valid and
figured out they're not. This can happen when there's a mismatch between
the JVM algorithm that performs the verification and the compiler
algorithm that generates the proofs. Which one is in your case I have no
idea.

I'm encountering this issue which I've never seen before, and was
wondering if someone could point me in the right direction. I have some
Akka streams 2.4.10 code (with Scala 2.11.8) that is embedded into a
GlassFish 4.0 server running Oracle Java 1.8.0_131-b11. All this is
wrapped into a Docker container for deployment that uses the Ubuntu as
the base image. Things were all working great for a while, but something
appears to have changed that is causing us some grief.
The docker image is built with the latest Oracle Java 8 JDK and base OS
(Ubuntu 14.04). When we needed to rebuild the image with a minor
configuration change, we are now consistently getting the following error:

And this is all kicked off just by calling this line of code:
implicit val actorSystem = ActorSystem("tsfs")
This far, I tried various versions of the base OS and tried updating
Akka with zero effect. Any suggestions would be greatly appreciated!
Thank you,
James
