Bug ID: 58059
Summary: Value for @PathParam annotated variable in @OnOpen is
not correct
Product: Tomcat 8
Version: 8.0.23
Hardware: PC
Status: NEW
Severity: major
Priority: P2
Component: WebSocket

Test projects to show @PathParam issues
When connecting to a websocket server endpoint in Tomcat 8.0.23, the mechanism
for populating a @PathParam annotated variable in the @OnOpen method does not
appear to be thread safe.
I have set up 2 test projects; one that is a single class container
web-application that handles websockets, and a client that connects to said
websocket.
When multiple requests come in with different path params, the value that is
passed on to the @OnOpen annotated method into the @PathParam annotated
variable does not match the value that is found in the
Session.getPathParameters() collection for the same session. It appears that
the @PathParam annotated variable is being overwritten with another connection
request's path param.
Here is some sample output from the attached "WebsocketPathParamIssueClient"
project showing the path param that was sent, what was set in the @PathParam
annotated variable, and what is in the Session.getPathParaters() collection:
