11 if only for amusement purposes :-) Capturing 9 out of 10 cases seems reasonable to me i.e. 5 entries. Perhaps a common case for r > 5 entries is a map for the primitive types and ref (ignoring “void”), which would push the limit up to 9 entries. I took a quick browse through the JDK and it is not that common AFAICT. j.l.invoke tends to use enums for example. There are two cases in java.ObjectInputStream and sun.misc.ProxyGenerator. Paul.
