When compiling JavaFX with Java 25, a new warning appears. This warning will
result in a compilation failure because warnings are treated as error
(`-Werror`).
The following warning appears:
> Task :controls:compileJava
C:..\jfx\modules\javafx.controls\src\main\java\javafx\scene\control\SplitPane.java:320:
warning: [identity] use of a value-based class with an operation that expects
reliable identity
private final WeakHashMap<Integer, Double> dividerCache = new
WeakHashMap<>();
^
C:..\jfx\modules\javafx.controls\src\main\java\javafx\scene\control\SplitPane.java:320:
warning: [identity] use of a value-based class with an operation that expects
reliable identity
private final WeakHashMap<Integer, Double> dividerCache = new
WeakHashMap<>();
^
error: warnings found and -Werror specified
1 error
2 warnings
> Task :controls:compileJava FAILED
The warning makes sense: We use a `WeakHashMap` with the `Integer` class. So
the `Integer` values are saved as `WeakRef` inside the `Map`. This makes no
sense and is rightfully a warning.
