Summary

Allow the SafeVarargs annotation to be used on private methods.

Problem

One of the rough edges of Project Coin is that @SafeVarargs cannot be applied to a private instance method even though private instance methods cannot be overridden, just like final instances methods and static methods where @SafeVarargs can be applied.

Solution

Add the capability for @SafeVarargs to be used on

Specification

In the javadoc of the java.lang.SafeVarags annotation, change

"... it is a compile-time error if a method or constructor declaration is annotated with a @SafeVarargs annotation, and either:

the declaration is a fixed arity method or constructor the declaration is a variable arity method that is neither static nor final."

to

"... it is a compile-time error if a method or constructor declaration is annotated with a @SafeVarargs annotation, and either:

the declaration is a fixed arity method or constructor the declaration is a variable arity method that is neither static nor final nor private."

In JLS 9.6.3.7 on SafeVarags, make the following change:

-It is a compile-time error if a variable arity method declaration that is neither static nor final is annotated with the SafeVarargs annotation.
+It is a compile-time error if a variable arity method declaration that is neither static nor final nor private is annotated with the SafeVarargs annotation.
