GROOVY-8067: Possible deadlock when creating new ClassInfo entries in the cache While I have been able to replicate the deadlock between `GroovyClassValuePreJava7$Segment` and the `GlobalClassSet#add`, I have not directly observed one between the `modifiedExpandos` and the `GlobalClassSet`, but think that it would be good to isolate their reference processing too since both lock in their operations.
