Summary: Unhandled NullPointerException when trying to write to a
closed socket.
Product: Tomcat 6
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Description of the scenario:
Consider a client using web Messaging service with NIOConnector configured.
Suppose if the client is closed by the time server writes the response to the
socket, it throws a NPE. It appears that there is no check for the null socket
condition. I think the addition of a null check will correct this.
The stack trace of the exception is:
[ActiveMQMessageConsumer] Exception while processing message:
java.lang.NullPointerException
java.lang.NullPointerException
