Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in the tomcat package. When a web application sends a WebSocket message concurrently with the WebSocket connection closing, the application may continue to use the socket after it has been closed. In this case, the error handling triggered could cause the pooled object to be placed in the pool twice. This issue results in subsequent connections using the same object concurrently, which causes data to be potentially returned to the wrong user or application stability issues.

If a web application sends a WebSocket message concurrently with the WebSocket connection closing, it is possible that the application will continue to use the socket after it has been closed. The error handling triggered in this case could cause the a pooled object to be placed in the pool twice. This could result in subsequent connections using the same object concurrently which could result in data being returned to the wrong use and/or other errors.
