[KSP2] Calling getDeclarationsInSourceOrder throws KotlinIllegalStateExceptionWithAttachments

[kuanyingchou]

This is another test case in XProcessing. Calling getDeclarationsInSourceOrder on a Java class implementing a Kotlin interface throws KotlinIllegalStateExceptionWithAttachments. If the sources are compiled then it works.

This issue appears to have been fixed, can you help me confirm?

[neetopia]

maybe not, but I can't seem to reproduce the issue with your repro.

[kuanyingchou]

Oops, sorry I moved the files to a lib module to test compiled origins and forgot to move them back. I just tried the latest main and can still reproduce.

created upstream issue for this: https://youtrack.jetbrains.com/issue/KT-69070

[neetopia]

Simply removing this line seems to help: https://github.com/JetBrains/kotlin/blob/cff91084f650490747a650869cbf9e3e316f1e93/compiler/fir/providers/src/org/jetbrains/kotlin/fir/scopes/impl/FirFakeOverrideGenerator.kt#L668

on the other hand, in the debugger, at the exception site, the status of the fir symbol is in resolve phase of TYPE which caused the failure in check.

It seems that the Kotlin parent has to be generic. Here's another repro with declarations call:

The upstream issue was fixed last week and we are waiting for the next compiler update. build-2.1.0-dev-4693

Verified with Kotlin 2.1.0-dev-5441.
