Bug ID: 64153
Summary: ServerContainer is not available in ServletContext
Product: Tomcat 9
Version: 9.0.31
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: WebSocket
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: -----
After updating Tomcat from 9.0.30 to 9.0.31 our integration tests don't even
start. Running Tomcat 9.0.31 in production works fine. In the integration tests
we use "org.apache.tomcat.embed:tomcat-embed-websocket" so I guess the issue is
somewhere there.
We use CometD and upon boot, the following exception is raised:
```

```
The error is coming from this line:
https://github.com/cometd/cometd/blob/3.1.12/cometd-java/cometd-java-websocket/cometd-java-websocket-javax-server/src/main/java/org/cometd/websocket/server/WebSocketTransport.java#L70
This is our initialization code:
```
tomcat = Tomcat.new
tomcat.port = @port
tomcat.connector.add_upgrade_protocol(Http2Protocol.new) # this will create the
default connector
base_path = java.nio.file.Path.of(Dir.tmpdir, 'project/webapp').to_string
root_ctx = tomcat.add_context('/project', base_path)
root_ctx.add_mime_mapping('css', 'text/css')
root_ctx.add_mime_mapping('js', 'application/javascript')
root_ctx.loader = WebappLoader.new(JRuby.runtime.jruby_class_loader)
ctx_cfg = ProjectContextConfig.new
ctx_cfg.default_web_xml = tomcat.no_default_web_xml_path
root_ctx.add_lifecycle_listener(ctx_cfg)
tomcat.start
```
I have no clue what could have changed and what is broken. Any suggestions as
to how do I debug this would be appreciated.
