Is it possible to solve the “A generic array of T is created for a varargs parameter” compiler warning?

Question

This is a simplified version of the code in question, one generic class uses another class with generic type parameters and needs to pass one of the generic types to a metho

Answer 1

Other than adding @SuppressWarnings("unchecked"), I don't think so.

This bug report has more information but it boils down to the compiler not liking arrays of generic types.

Answer 2

You can add @SafeVarargs to method since Java 7, and you don't have to annotate on client code.

class Assembler<X, Y> {

    @SafeVarargs
    final void assemble(X container, Y... args) {
        //has to be final...
    }
}
