[PROPOSAL] Drop comet support in Tomcat 9 onwards
I have been thinking about connector refactoring for Tomcat 9. Currently
BIO is planned to be dropped due to the number of features in the
servlet spec that rely on non-blocking IO.
I would like to propose dropping support for Comet in Tomcat 9 onwards.
The reasons are:
- WebSocket is already far more popular (based on question volume on the
users list)
- Comet support adds a fair amount of complexity to the connector code
Thoughts?
Keep in mind that 8.0.x isn't stable yet and any 9.0.x is likely to be
several years away.

Check the date on the original message.
The first stable 8.0.x release was 8.0.9 on June 24 2014, 6 days after I
sent that message.

+1 to remove Comet from 9.0.x.
Tomcat 8 isn't stable? (!)
