Grails dynamic finder InList has incorrect incompatible types inspection when passing a non-List collection

The Grails "findAllBy…InList" supports any Collection as can be seen here: [https://github.com/grails/grails-data-mapping/blob/c4ef4d0348848cbf4b54783b79b6c694b7b3aae1/grails-datastore-gorm/src/main/groovy/org/grails/datastore/gorm/finders/MethodExpression.java#L270](https://github.com/grails/grails-data-mapping/blob/c4ef4d0348848cbf4b54783b79b6c694b7b3aae1/grails-datastore-gorm/src/main/groovy/org/grails/datastore/gorm/finders/MethodExpression.java#L270)

When attempting to pass a Set (or any other collection), IDEA shows an inspection error saying 'findAllBy…InList' in '…' cannot be applied to '(…)'

Start by reading MethodExpression.java around line 270, where the InList collection behavior is shown, then trace the IntelliJ inspection that reports incompatible argument types for findAllBy…InList. Done means passing a Set or another non-List Collection no longer produces the incorrect inspection error.
