As we agreed, I enter this bug contribution into the main bugtracking system. The problem is also exhibited if we define class java.lang.Object in Scala. Then there's a "error overriding method ..." message (no crash).

Defining java.lang.String is now ok. Defining java.lang.Object crashes the compiler (issues "illegal cyclic reference involving class Object" first).
