It seems the meaning of AnchorLocation is opposite to all other position/location parameters in JavaFX when using RTL orientation: in javafx.geometry.Pos, javafx.geometry.HPos LEFT always means "start", so in RTL orientation it aligns nodes to the right (i.e. start of read order).
In AnchorLocation however, LEFT and RIGHT have absolute meanings, regardless of node orientation. The comment in [1] says this is how it should work, but considering this is opposite to how other parts of JavaFX operate and that in RTL orientation the default behavior should be anchoring to the right, I think it may be a problem. At the very least, perhaps clarify in the documentation of AnchorLocation that its meaning differs from Pos etc.? Thanks, Itai.
