JwsJsonContainerRequestFilter throws exception in case of DELETE method invocation with empty payload

Below is the stack trace. As GET method does not has such an issue, I looked into JwsJsonContainerRequestFilter and found JWS is pypassed in case of GET method. I think DELETE should also bypass the check. (Note that when DELETE method has an empty response, JWS should also be bypassed)

public class JwsJsonContainerRequestFilter extends AbstractJwsJsonReaderProvider implements ContainerRequestFilter {
@Override
public void filter(ContainerRequestContext context) throws IOException {
if (HttpMethod.GET.equals(context.getMethod())

{ return; }
