We have a J2EE application, which has a front end developed in Java Swing with usage of heavy graphics & managed by the weblogic server. There are several application details in the Hash-Maps containing with nested Hash-Maps & Hash maps contains the Serializable Java Value Objects. These serializable Java Objects contains values which are Java Primitive Types as well as Other Java Value Objects. When the client launches the application & tries to read these Hash-Maps from the server, the Stack Over Flow Exception as given below occurs. This has started occurring from a few days only.
Stack Trace :
java.lang.StackOverflowError at java.io.ObjectOutputStream.outputClassFields(ObjectOutputStream.java:1812) at java.io.ObjectOutputStream.defaultWriteObject(ObjectOutputStream.java:480) at java.util.HashMap.writeObject(HashMap.java:798) at java.lang.reflect.Method.invoke(Native Method) at java.io.ObjectOutputStream.invokeObjectWriter(ObjectOutputStream.java:1864) at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:1210) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:366) at java.io.ObjectOutputStream.outputClassFields(ObjectOutputStream.java:1827) at java.io.ObjectOutputStream.defaultWriteObject(ObjectOutputStream.java:480) at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:1214)
Can you suggest something in this regard? This is VERY URGENT !!
Hi, I am not sure why this is happening in your application but in genral this happens in swing when there is a dead lock. Since swing is event driven, if for some reason there is an event that triggers another and that inturn triggers the first one, then you end up with Stack overflow exception. Hope this helps.
