------------------------------------
Summary: SerializationDebugger does not handle classes with
writeReplace correctly
Key: SPARK-8090
URL: https://issues.apache.org/jira/browse/SPARK-8090
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.4.0
Reporter: Tathagata Das
Assignee: Tathagata Das
Priority: Minor
The following class with not serializable object used through writeReplace will
not be caught correctly by the SerializationDebugger
{code}
class SerializableClassWithWriteReplace()
extends Serializable {
private def writeReplace(): Object = {
new NotSerializableObjectI()
}
}
{code}
The reason is that SerializationDebugger does not check the type of the
replaced object (whether serializable or not).
