On trying to edit it a WinL&F JTree Parent node, the icon toggles to collapsed state.

On trying to edit it a WinL&F JTree Parent node, the icon toggles to collapsed state.
Steps to reproduce:
1)Run Swigset2,tab to the JTree Demo, switch to Windows L&F.
2)Click to select the node called "Rock".Observe that the folder icon against the "Rock" node becomes expanded.
3)Press F2.
Actual behavior:
The Node "Rock" becomes editable, the folder icon against the "Rock" node becomes collapsed.
Expected behavior:
The Node "Rock" becomes editable, the folder icon against the "Rock" node remains in the same state sa it was before i.e in expanded state as is the case for a native windows explorer folder icon.
This is seen on jdk6 b104 build.
Attatched is the screen shot of the incorrect behavior.
