Thank you for your reply.
I've just created an issue - Add Stage.setMaximizable(boolean) API for
decorated and extended stages in JavaFX

There's no API to disable the double-click to maximize behavior for an
extended stage, much in the same way as there's no API to do that for
a decorated stage. Since an extended stage is just a decorated stage
with a customizable title bar, any solution to toggle the double-click
to maximize behavior should apply to both stage styles.
Maybe we can have an API like Stage.setMaximizable(boolean) to toggle
the maximizable capability (this would be different from the existing
Stage.setMaximized(boolean), which toggles a state, not a capability).
We should discuss this feature request in terms of both decorated and
extended stage styles.
