@JsonbCreator with static factory method and generic type fails

[f-wunderlich]

Might be related to #599, but the symptoms are different and the proposed workaround does not work. Take the example posted there, but with a static factory method:

public class RuleResponse<T> {
    private T result;

    @JsonbCreator
    public static <T> RuleResponse<T> of(@JsonbProperty("result") T result) {
      final RuleRespone<T> response = new RuleRespone<T>();
      response.result = result;
      return response;
    }

    public T getResult() {
        return result;
    }
}

Then,

JsonbBuilder.create().fromJson(
  expectedJson, 
  new TypeLiteral<RuleResponse<Integer>>() {
    private static final long serialVersionUID = 1L;
  }
  .getType()
);

attempts to set RuleResponse#result to a BigDecimal instead of an Integer.

This is caused by VariableTypeInheritanceSearch#searchRuntimeTypeArgument due to this block:

        if (ReflectionUtils.getRawType(runtimeType) != typeVar.getGenericDeclaration()) {
            return null;
        }

typeVar.getGenericDeclaration() returns a Method, thus that test will always fail. It is unclear why this test is there. Simply removing it should result in correct resolution.
