Right now if we call setEnabled(false) over JSplitPane than it can't be dragged via its divider, But if SplitPane have one touch expandable true than user can click those buttons and change the divider position.
Call of setEnabled(false) shouldn't be partially effective like this.
Attached testcase TestJSplitPane2.java it shows this problem and one can change
L*F in testcase and see this problem is reproducible in all L&F's

Reproducible in tiger b44
