Summary: Null Pointer Exception in InternalOutputBuffer
Product: Tomcat 5
Version: 5.5.9
Platform: PC
OS/Version: other
Status: NEW
Severity: major
Priority: P2
Component: Connector:HTTP
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: spadala@sbcglobal.net
When the servlet output stream is pooled for future use, any writes followed
with a flush to the output stream (obtained from the pool) are causing null
pointer exceptions.
* Same problem exists with PrintWriter.
* The writes+flush to the output stream are not happening on the thread that
received the initial service request.
* There is a server listening on the other side of HTTP socket.
* Is the original service thread cleaning up the output stream?
Platform : Windows XP PRofessional
Java Version : jdk 1.5.0_04
Apache Tomcat Version 5.5.9
