I don't think so .. it was documenting the Nimbus default which is continuous.
Per the javadoc for 
https://docs.oracle.com/en/java/javase/17/docs/api/java.desktop/javax/swing/JSplitPane.html#setContinuousLayout(boolean)

" The default value of this property is look and feel dependent."

So if Nimbus has had it ON all this time, it is not right to change it.
