java exception during first attempt to do REPL completion by TAB in sbt console on Scala 3.4.1

[bjornregnell]

Compiler version

Use Scala 3.4.1 and any sbt of version 1.9.8, 1.9.9, 1.10.0.

Minimized code

Start the console and type Seq. and press TAB for completion.

Output

exception caught when loading class module-info: java.lang.AssertionError: assertion failed: attempt to parse java.lang.Object from classfile

Expectation

no exception

[bjornregnell]

Same as this issue cross-posted here on request by @smarter :
sbt/sbt#7560

As the root cause might be here and not in sbt.

[smarter]

module-info.class is a magic JPMS thing generated from the also magic module-info.java that doesn't behave like a regular classfile. We should not even try to load it because - is not valid in a classfile name, so it should be skipped over.

[bjornregnell]

So scala-cli has some smarter loading logic here? Or why does 3.4.1 work when REPL from scala-cli?

[smarter]

It has to do with how classpaths are setup but I don't know where the difference comes from. Running with -Ylog-classpath might give more information.

exception caught when loading class module-info: java.lang.AssertionError: assertion failed: attempt to parse java.lang.Object from classfile

[bjornregnell]

Running with -Ylog-classpath might give more information.

Indeed more information... Sorry for spamming many lines here.

[bjornregnell]

@smarter can you reproduce it on your machine?
(Just type Seq. in sbt console and press TAB and it should show the exception)

[SethTisue]

@bishabosha is it possible this has to do with the pipelining changes somehow...? didn't "module-info" come up in that context not long ago?

[smarter]

@smarter can you reproduce it on your machine?

Yes.
