Updating an OS costs money (if it is Windows) and may be not possible
due to hardware limitations.

That said, reviewing the changes and comments once again,
I see that this is not a showstopper for Windows XP users, if there are any.

The comments say about reduced performance, not an inability to run Tomcat.
The pollset size can be adjusted by configuring maxConnections="1024"
or less. I think that is a reasonable value for some legacy server.

Thus OK to backport to Tomcat 7.

Looking into documentation,
Regarding maxConnections it says
"Note that for APR/native on Windows, the configured value will be
reduced to the highest multiple of 1024 that is less than or equal to

I think that is no longer true.
