jfx25u open for JavaFX 25.0.1 backports

[Kevin Rushforth]

All,

The jfx25u repo [1] is now open for JavaFX 25.0.1 backports (the October 
2025 CPU release), with approval from one of the project leads. The 
general criteria is that we want to backport fixes for regressions 
introduced in JavaFX 25, third-party library updates, and a limited 
number of other important bug fixes. In most cases we'd like to see the 
fix "bake" in the mainline for a while before being backported to jfx25u.

NOTE: Only those fixes that will NOT be backported to the jfx25 [2] 
stabilization branch are candidates for backporting to jfx25u. A 
backport intended for the JavaFX 25 code line will go into either the 
jfx25 branch or the jfx25u repo, not both.

We use a similar procedure for making the request and noting the 
approval as is used by the JDK updates releases -- by using JBS labels 
to request a backport and indicate approval or rejection.

Here is the procedure:

1. If you are not sure whether something is a good candidate for 
backporting, ask on the mailing list or in the PR you want to backport.

2. Create the backport PR for jfx25u, either manually or using the 
"/backport" command. You can use Skara's "/approval" command to request 
approval. Skara will not mark a jfx25u PR as ready until approved.

Let Johan or me know if you have any questions.

Thanks.
