Thinking out load: I'm wondering if it's better for java developer to either use
Slider<T extends Number> or IntSlider / DoubleSlider.
Having to deal with double all the time when I just have a simple 0-5 slider feels awkward. (Same could be said for min/max and step.. might be good to add overloaded methods?)

Valid point, thank you. We could add an IntegerSlider later
Add a utility method to schedule actions that run before the client response, with deduplication by key. This allows deferring state validity checks until all property changes are complete. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Log warnings when setMin, setMax, or setStep is called and the current value becomes inconsistent with the new constraints. The warnings are deferred using beforeClientResponse to check the final state after all property changes in the current request are complete. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add tests verifying that warnings are logged when value doesn't align with min, max, or step constraints after property changes. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Change SliderBase constructor from protected to package-private. Update SliderTest to use the 4-parameter constructor with step value. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add constructors that use default step value of 1: - Slider(min, max, value) - Slider(min, max, value, listener) - Slider(label, min, max, value) - Slider(label, min, max, value, listener) Add corresponding unit tests verifying step defaults to 1.

Let's register Mockito as an agent explicitly as is done here: #8478.

Update SliderBase to use SerializableBiFunction for value converters, allowing subclasses to access component state during conversion. Remove unused constructor and inline init method. Update Slider to validate values during conversion and throw exceptions for invalid min/max/step changes. Remove SliderWarningsTest as warnings are replaced with exceptions. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add tests for IllegalArgumentException scenarios: - setValue with value not aligned to step - setValue with null value (NullPointerException) - setMin greater than current value - setMax less than current value - setStep with negative value - setStep when current value is not aligned Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
…n Slider Remove setMin, setMax, setStep methods from Slider and add setValue overloads that update min, max, step, and value atomically. This avoids validation errors when changing multiple properties that depend on each other. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Replace setStep() call with constructor that accepts step parameter, as setStep is no longer public. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
