Smoke-testing examples webapp of Tomcat 8.0.46 Release Candidate
Configuration:
Java 7u80, configured connector to use NIO protocol
Steps to reproduce:
1. Start Tomcat with SecurityManager enabled
> catalina.bat start -security
2. Go to 'Examples' page, click on Websocket examples
http://localhost:8080/examples/
http://localhost:8080/examples/websocket/index.xhtml
3. Open 4 websocket examples in new browser tabs
http://localhost:8080/examples/websocket/echo.xhtml
http://localhost:8080/examples/websocket/chat.xhtml
http://localhost:8080/examples/websocket/snake.xhtml
http://localhost:8080/examples/websocket/drawboard.xhtml
Result: Snake and Drawboard examples fail immediately, printing "WebSocket
connection closed" messages into their log areas.
