Bug ID: 59177
Summary: Throw IOException each time close websocket session
Product: Tomcat 7
Version: 7.0.68
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: WebSocket

sample websocket app
- Each time a websocket session is closed, it always throw IOException.
The reason is when WSSession#onClose method is called, and it changes the state
to State.CLOSING, but the WSSesssion#registerFuture fail the checking state, if
the State is not OPEN, it throw exception
- This bug not happen on Tomcat 7.0.63
- I have attached the sample app that use websocket, this sample is the "Echo"
sample downloaded from Tomcat document page.
- Steps to reproduce issue:
+ Deploy app and go to : http://localhost:8080/wsSample/test.html
+ Connect, send messsage
+ Disconnect --> Throw IOException in tomcat error log
- I guess we should instead check State is not close instead of is OPEN in
WSSesssion#registerFuture
