Hi,

I encountered the following exception:
{code}

Code that reproduces the problem:
{code:java}
package flink.bug;

import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;
import org.apache.flink.streaming.api.functions.sink.SinkFunction;
import org.apache.flink.streaming.api.windowing.time.Time;

public class App {

    public static void main(String[] args) throws Exception {
        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

        env.setParallelism(2);

        env.fromElements(1, 2)
            .map(Aggregate::new)
            .keyBy(Aggregate::getKey)
            .timeWindow(Time.seconds(2))
            .reduce(Aggregate::reduce)
            .addSink(new CollectSink());

        env.execute();
    }

    private static class Aggregate {

        private Key key = new Key();

        public Aggregate(long number) {
        }

        public static Aggregate reduce(Aggregate a, Aggregate b) {
            return new Aggregate(0);
        }

        public Key getKey() {
            return key;
        }

    }

    public static class Key {
    }

    private static class CollectSink implements SinkFunction<Aggregate> {

        private static final long serialVersionUID = 1;

        @SuppressWarnings("rawtypes")
        @Override
        public void invoke(Aggregate value, Context ctx) throws Exception {
        }
    }
}
{code}

Attached is the project that can be executed with {{./gradlew run}} showing the problem, or you can run the attached {{flink-bug-dist.zip}} which is prepackaged with the dependencies.

Thanks in advance
