Compatibility with JPMS

[Burtan]

Hey,
it seems that this module uses internal functions of kotlin.reflect and thus is incompatible with the JPMS:

Caused by: java.util.ServiceConfigurationError: kotlin.reflect.jvm.internal.impl.builtins.BuiltInsLoader: module merged.module does not declare `uses`

[SR-Lut3t1um]

This problem just cost me around 20 hours while trying to debug a JavaFX/GraalVM application. Hopefully someone reads this and doesn't have to waste the same amount of time :/

[dinomite]

@SR-Lut3t1um What version of Jackson are you using? I believe this was fixed in #393, released with Jackson 2.12.0. I'm able to build & run jackson-module-kotlin's tests using Azul Zulu 16.

Oddly, Maven actually tells me that the kotlin.reflect declaration in the module-info.java is unused:

[WARNING] Bundle com.fasterxml.jackson.module:jackson-module-kotlin:bundle:2.13.0-rc3-SNAPSHOT : Unused Import-Package instructions: [kotlin.reflect.*]

Despite the fact that we use kotlin.reflect.jvm.internal.KotlinReflectionInternalError in https://github.com/FasterXML/jackson-module-kotlin/blob/2.13/src/main/kotlin/com/fasterxml/jackson/module/kotlin/KotlinNamesAnnotationIntrospector.kt#L25

[SR-Lut3t1um]

@dinomite I'm using the 2.12.4 version. Also made a simple reproducer

[dinomite]

I'm unable to make the reproduction run. I've never used GraalVM, but here it is failing in the same way under Azul Zulu & GraalVM. This is on a Linux host.

Running under Azul Zulu 11.0.12:

[SR-Lut3t1um]

Did you try to run the example in a Environment without a Window Manager?

[dinomite]

@SR-Lut3t1um Oh yes, and there error does seem to imply that's a problem. I can give this a try in a VM, or if you can make a reproduction that doesn't require graphics I'll get to it much more quickly.

[k163377]

The changes made by @cowtowncoder may work in 3.x.
#888 (comment)

[cowtowncoder]

I think this can be closed: for 3.0 proper module-info.java, but with 2.18.x via Moditect things should work too.
