A divider can be no less than one pixel in size.

// Create a left-right split pane
JSplitPane pane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, leftComponent, rightComponent); // Get current size; it is look and feel dependent
int size = pane.getDividerSize(); // Set a new size
size = 1;
pane.setDividerSize(size);
