Unable to get results from pipeline after tx discard

[jencompgeek]

The following code throws Exceptions attempting to get results of a pipelined operation after pipeline.discard() has been called. It looks like the discard op and all future ops are still getting added to the currentMulti ResponseBuilder. I'm seeing this with Jedis 2.1.0.

@Test
    public void testDiscard() {
        Jedis jedis = new Jedis(new JedisShardInfo("localhost", 6379));
        jedis.connect();
        Pipeline pipeline = jedis.pipelined();
        pipeline.multi();
        pipeline.set("foo", "bar");
        Response<String> discard = pipeline.discard();
        Response<String> get = pipeline.get("foo");
        pipeline.sync();
        // Both gets below throw RedisDataException Please close pipeline or multi block before calling this method
        discard.get();
        get.get();
    }
