R8 failure with 0.84.2

No issue with 0.84.0

$ ./gradlew assembleRelease

The best workaround for me is to prevent EventType from being obfuscated/optimized by adding the following line to the proguard rules:

-keep public enum nl.adaptivity.xmlutil.EventType {*;}

With this workaround I can use the latest versions of XmlUtil and AGP.

I can confirm it is certainly a problem with r8. I managed to isolate it to a single line: https://github.com/pdvrieze/xmlutil/blob/ff63f4534fcf639f00a659ae34945763cfd6b5bf/core/src/commonMain/kotlin/nl/adaptivity/xmlutil/core/KtXmlReader.kt#L260

Removing the line will make it work, moving it to be next to the similar line for EndDocument doesn’t.
