Doug Cutting commented on AVRO-1923:
------------------------------------
Elsewhere in Avro we handle circular structures by keeping track of previously
seen objects, with no limit on the depth of circularity. So this might instead
look something like:
{code}
public String toString(Object o, StringBuffer b) {
return toStringInternal(o, b, new IdentityHashMap());
}
public String toString(Object o, StringBuffer b, Map seen) {
if (seen.containsKey(o))
return ... ; // circle detected
try {
seen.put(o, o);
... prior toString logic ...
} finally {
seen.remove(o);
}
}
{code}
> Recursive record causes StackOverflow in GenericData.toString
