I'm having a weird issue where latest -RC (anything >= 1.8.20-RC-243) show Java 19 warnings (and fail with allWarningsAsErrors ). My JAVA_HOME is 19 but I'm supposed to compile with a 17 toolchain and target 1.8 (failed CI run). Does that ring a bell to anyone?

[mbonnin]

Also is it ok to report -RC-foo issues here? Given they're certainly not as tested as the proper EAPs, is it still worth reporting this?

[tapchicoma]

yes, please report

[tapchicoma]

generally -RC-foo should be stable

[mbonnin]

Want me to open a Youtrack or here is fine?

[tapchicoma]

let me quickly check the issue

[mbonnin]

git clone and ./gradlew compileKotlin (using Java 19 as JAVA_HOME) should reproduce it

[tapchicoma]

have you seen it with 1.8.20-Beta? 🤔

[mbonnin]

No, 1.8.20-Beta is fine

[mbonnin]

I bisected to RC-243 (RC-237 is fine)

[tapchicoma]

interesting, there were no changes in regard of toolchain handling 🤔

[tapchicoma]

Compilation definitely receives correct JDK: [KOTLIN] Kotlin compilation 'jdkHome' argument: /opt/openjdk-bin-17.0.6_p10

[mbonnin]

Could it be a daemon thing?

[mbonnin]

I put kotlin.compiler.execution.strategy=in-process in that project but not sure if it changes anything

[tapchicoma]

this actually runs without Kotlin daemon

[tapchicoma]

with Kotlin daemon I also see such error

[tapchicoma]

please create a new YT issue - seems to be compiler problem

FYI: found the cause - should be fixed before RC

[mbonnin]

Nice, thanks!
