aa....aa: Stack trace of the exception

Description

The stack trace of the exception thrown during the serialization of the global session information will be output row-wise.

Take action based on the following causes of failure in the serialization:

• The object referenced from the object registered in the HTTP session (object of a serializable class) is not from a serializable class.
• The writeObject(java.io.ObjectOutputStream out) method is implemented and an exception occurred during the serialization.

Action

Determine the cause of the failure in serialization based on the contents of the stack trace, and then take either of the following actions:

• Remove the object in which the error has occurred from the effect of redundancy.
• Change the application, and then remove the cause of the error.
