> Infinite recursion on TypeExtractor
> -----------------------------------
>
> Key: FLINK-3922
> URL: https://issues.apache.org/jira/browse/FLINK-3922
> Project: Flink
> Issue Type: Bug
> Components: Type Serialization System
> Affects Versions: 1.0.2
> Reporter: Flavio Pompermaier
> Assignee: Timo Walther
> Priority: Critical
>
> This program cause a StackOverflow (infinite recursion) in the TypeExtractor:
> {code:title=TypeSerializerStackOverflowOnRecursivePojo.java|borderStyle=solid}
> public class TypeSerializerStackOverflowOnRecursivePojo {
> public static class RecursivePojo<K,V> implements Serializable {
> private static final long serialVersionUID = 1L;
>
> private RecursivePojo<K,V> parent;
> public RecursivePojo(){}
> public RecursivePojo(K k, V v) {
> }
> public RecursivePojo<K, V> getParent() {
> return parent;
> }
> public void setParent(RecursivePojo<K, V> parent) {
> this.parent = parent;
> }
>
> }
> public static class TypedTuple extends Tuple3<String,String, RecursivePojo<String, Map<String, Set<String>>>>{
> private static final long serialVersionUID = 1L;
> }
>
> public static void main(String[] args) throws Exception {
> ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();
> env.fromCollection(Arrays.asList(new RecursivePojo<String, Map<String, Set<String>>>("test",new HashMap<String, Set<String>>())))
> .map(t-> {TypedTuple ret = new TypedTuple();ret.setFields("1", "1", t);return ret;}).returns(TypedTuple.class)
> .print();
> }
>
> }
> {code}
> The thrown Exception is the following:
> {code:title=Exception thrown}
> Exception in thread "main" java.lang.StackOverflowError
