SecurityManager
Product: Tomcat 9

Smoke-testing Tomcat 9.0.20 release candidate:
running apache-tomcat-9.0.20-windows-x64.zip + OpenJDK Java 12.0.1 64-bit on
Windows 10.
WebSocket examples are failing and are not usable.
1. I opened all websocket examples in different tabs.
2. Testing the "echo" example:
1) The "Connect" button works, a connection is opened.
2) Messages are sent to the server ("Sent: Here is a message!" line is
printed), but there is no echo from server (nothing is received).
3) The "Disconnect" button does not work.
4) The connection closes itself after a timeout. The following is printed:
"Info: WebSocket connection closed, Code: 1006"
3. Other WebSocket examples fail to initialize. They open a connection but fail
to operate any further.
4. If I run the same version of Tomcat and Java without enabling a
SecurityManager, the WebSocket examples work correctly.
BTW, other examples work correctly. Running them with SecurityManager being
enabled I do not note any issues.
