Comments
EVALUATION The test fails after the fix for 6706212. The cause is in the following lines: src/share/classes/javax/swing/plaf/basic/BasicSplitPaneUI.java @@ -328,12 +328,13 @@ setOrientation(splitPane.getOrientation()); // This plus 2 here is to provide backwards consistancy. Previously, // the old size did not include the 2 pixel border around the divider, // it now does. - LookAndFeel.installProperty(splitPane, "dividerSize", - UIManager.get("SplitPane.dividerSize")); + Integer dividerSize = (Integer)UIManager.get("SplitPane.dividerSize"); + if (divider == null) dividerSize = 10; + LookAndFeel.installProperty(splitPane, "dividerSize", dividerSize); divider.setDividerSize(splitPane.getDividerSize()); dividerSize = divider.getDividerSize(); splitPane.add(divider, JSplitPane.DIVIDER); As you can see, dividerSize local variable is introduced. However, BasicSplitPaneUI has dividerSize field. In the same method where the local variable is declared there is some code working with the field. After the fix the code logic was broken. It is the cause. The fix is simple. We should rename the local variable.
