> Consider the following:
> {code:java}
> interface I {}
> class C<T extends Number & I> { T meth() {} }
> class X extends C<Integer> {} // should produce error "The type Integer is not a valid substitute for the bounded parameter <T extends java.lang.Number & I>"
> new C<Integer>() // should produce error "The type Integer is not a valid substitute for the bounded parameter <T extends java.lang.Number & I>"
> {code}
> If the type bound Number is not satisfied, an error is produced.  However, failure to satisfy the additional interface(s) does not produce a compiler error.
