Major Tomcat versions are tied to Java EE releases.
Current policy is to support 3 major versions in parallel.
Current policy is to provide at least 12 months notice for EOL for any
major release.
So,
Tomcat 9 supports Java EE 8
Tomcat 8 supports Java EE 7
Tomcat 7 supports Java EE 6
With the move of Java EE to Eclipse and EE4J (or whatever the name ends
up being) things are not quite as certain.
Oracle's/Eclipse's intention, as I currently understand it, is as follows:
1. Transfer everything to Eclipse
2. Release essentially the same stuff as Java EE 8 but under the EE4J
name, ensuring it passes the Java EE 8 TCK. Call it EE4J v1.0
3. Do an update to the specs and release EE4J vTBD
4. TBD - led by the community
1 & 2 won't trigger a new major Tomcat release as the specs won't have
changed.
3 might trigger a new Tomcat release (which would trigger EOL for Tomcat
7) depending on what is in that release.
My best guess right now is that:
- we will switch to tying major Tomcat releases to releases of the
Servlet specification
- any updates to the Servlet spec in 3 above will be more along the
lines of errata rather than new features so no new Tomcat version
- the first real update to the Servlet spec will be in step 4 above
In terms of timing, the earliest there could be a plan for a substantive
update to the Servlet spec is June 2018 with the earliest release for
that update being December 2018. If this happened, EOL for Tomcat 7
could be as early as 30 June 2019. At the moment, I don't think this is
realistic.
I think a more realistic timescale is 6 to 18 months later so EOL for
Tomcat would fall somewhere in the range 31 December 2019 to 31 December
2020.
However, most of the above is nothing more than guess work on my part.
What I can say for certain at the moment is:
- We will give at least 12 months notice.
- We have no plans for doing so at the moment
- Timing is going to be driven by what happens to Java EE at Eclipse
