I just updated to 4.8.0.v202210112349-e2209 in 4.25-SNAPSHOT. I have an annotation collector that includes @TupleConstructor, and the editor for the file shows this error at -1,-1:

@AnnotationCollector
@TupleConstructor
@interface ExampleData{}

Groovy:Error processing interface 'com.example.ExampleData'. @TupleConstructor not allowed for interfaces.

Any classes annotated with the collector annotation then have

Groovy:Expecting static method `Object[][] value()` in groovy.transform.Undefined$CLASS. Was it compiled from a Java source?

This does not appear to affect the actual .class output, and it doesn't show in the Package Explorer, but it's alarming the newbies.
