<folder name="Windows2">
<folder name="Modes">
<folder name="editor_hidden"/>
<file name="editor.wsmode_hidden"/>
</folder>
</folder>
So probably it's not really a fault and it should be closed as INVALID

adding run.args.extra=-J-Dnetbeans.winsys.hideEmptyDocArea=true produces an NPE at startup in a minimal application containing only one module with two TopComponent in two modes (both kind="view") java.lang.NullPointerException at org.netbeans.core.windows.ModeStructureSnapshot$EditorSnapshot.isVisibleInSplit(ModeStructureSnapshot.java:443) at org.netbeans.core.windows.ModeStructureSnapshot$EditorSnapshot.hasVisibleDescendant(ModeStructureSnapshot.java:451) at org.netbeans.core.windows.ModeStructureSnapshot$SplitSnapshot.getVisibleChildSnapshots(ModeStructureSnapshot.java:219) at org.netbeans.core.windows.view.ViewHelper.createSplitAccessor(ViewHelper.java:190) ... .... I get the same behaviour if I use System.setProperty("netbeans.winsys.hideEmptyDocArea", "true"); in the module Installer.
