For any response >= 400 Jersey will throw a UniformInterfaceException
unless the type declared is ContainerResponse.class.

The above will work irrespective of the status code and do what you
require.
Alternatively:
try {
String response resource.path("/test/
dummy").accept(MediaType.APPLICATION_JSON_TYPE).get(String.class);
} catch (UniformInterfaceException ex) {
// Check status
if (ex.getResponse().getStatus() >= 400) {
String getResponse()..getEntity(String.class);
}
}
The important thing to do when writing the client is check the status
code. This is why the Jersey client attempts to enforce a certain way
of working as often clients should react differently for different
status codes.
