java compiler error (class not found) when using scala dependency
Describe the bug When using Akka within a project that has manifold configured, the compiler throws the following error:
An exception has occurred in the compiler (17.0.7). Please file a bug against the Java compiler via the Java bug reporting page (https://bugreport.java.com/) after checking the Bug Database (https://bugs.java.com/) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.
com.sun.tools.javac.code.Symbol$CompletionFailure: class file for akka.actor.CoordinatedShutdown$tasks$$TaskDefinition$ not found
To Reproduce I forked the manifold-sample-project and added the akka dependency + a sample class using akka to reproduce the error: https://github.com/codejanovic/manifold-sample-project
Expected behavior I expected the project to compile correctly.

That is a confusing naming convention with akka/scala -- Name vs. Name$ etc. I'm not sure what is going on exactly, but it appears the akka.actor.CoordinatedShutdown$tasks$$TaskDefinition$ class is indeed missing from the jar or is otherwise not available, however it manifests. Perhaps there is another akka related jar dependency that defines it?
You are right, the type akka.actor.CoordinatedShutdown$tasks$$TaskDefinition$ exists within the scala code of akka, but i am also unable to find it within the jar. I will try to find out what is happening here and report back! Thanks for the fast response
It looks like the classes are not referenced in IntelliJ, but definetely present in the jar:
The missing type has a pair of $$:
akka.actor.CoordinatedShutdown$tasks$$TaskDefinition$
Is there anything i can help investigate with? Is there somewhere a contribution guide or sth like that? Didnt touch compiler plugins yet.
Although the compiler complains about ...$tasks$$TaskDefinition$, it works lilke a charme when manifold is not configured.

Good point. It must be something on my end. I’ll have another look at this.
Just checked that i'm not lying:
manifold disabled -> compiles: commit manifold enabled -> wont compile: commit
Hi @LinSanmu. Sorry, no it’s an issue that unfortunately fell by the wayside. I’ll put it back on my stack. Are you experiencing the same problem?
