If we are re-rolling, I would like to pull back Chris Schultz's
changes to CSRF Filter
(8c143abae26f9b0c49b233c3e7a9cb6cc5b1b0ed)
until all issues with those changes are solved on master (9.0).

Not a showstopper.

What is easier for you?
If 7.0.x needs a patch as well, won't it be easier to have the same
patch as for 7.0?

(For reference, discussion of the single poll set change on dev@, Jul 05 2019

Subject:Re: [tomcat] branch master updated: Quick fix for poller issue
reported on users list
)

The removed code is for older OSes like Windows XP. As stated in a
comment in that code (in AprEndpoint.java) the issue was solved in
Windows Vista,
Support for Windows XP ended April 8, 2014.  The first version of Java
8 was March 18, 2014, thus we are safe to assume that Tomcat 9 does
not run on Windows XP.

The first version of Java 7 was in 2011, thus I think that Tomcat 8.0
may run on Windows XP.

Tomcat 8.5.0 was released in March 2016, so I think it was never
really tested on Windows XP.  Looking into the "Vote" thread for
8.5.0, it was tested on Windows 7. Thus I have no objections against
backporting the single pollset change to Tomcat 8.5.

Officially, running Java 7 on Windows XP is no longer supported by
Oracle. For reference:
