Hiding folders that start with dot in Project Explorer in RCP Project

In my RCP project, I would like to programmatically hide the folders that starts with dot in the Project Explorer (when the user browse to open a file).

I have used the below extensions to achieve this, but sadly it did not work. Can someone help? Thank You.

<extension point="org.eclipse.ui.navigator.navigatorContent">
    <commonFilter
        description="Hides .* resources"
        id="com.xyz.commonFilter.hidePj"
        name=".* resources"
        activeByDefault="true">
        <filterExpression>
            <and>
                <adapt type="org.eclipse.core.resources.IResource">
                    <test property="org.eclipse.core.resources.name" value=".*"/>
                </adapt>
            </and>
        </filterExpression>
    </commonFilter>
</extension>

<extension point="org.eclipse.ui.navigator.viewer">
    <viewerContentBinding
          viewerId="org.eclipse.ui.navigator.ProjectExplorer">
          <includes>
           <contentExtension pattern="com.xyz.commonFilter.hidePj"/> 
          </includes>
    </viewerContentBinding>
</extension>

Note: I am using eclipse Ganymede.

Change the generic IResource type:

<adapt type="org.eclipse.core.resources.IResource">

and use the most specific IFolder type:

<adapt type="org.eclipse.core.resources.IFolder">

The relevant source code follows, standard Eclipse plugin project created with the wizard (Ganymede), I just changed the id name attribute:

plugin.xml:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>

  <extension point="org.eclipse.ui.navigator.navigatorContent">
    <commonFilter
        id="com.stackoverflow.commonFilter.hideFolders"
        name=".* folders"
        description="Hides .* folders"
        activeByDefault="true">
      <filterExpression>
        <and>
            <adapt type="org.eclipse.core.resources.IFolder">
              <test property="org.eclipse.core.resources.name" value=".*"/>
            </adapt>
        </and>
      </filterExpression>
    </commonFilter>
  </extension>

  <extension point="org.eclipse.ui.navigator.viewer">
    <viewerContentBinding viewerId="org.eclipse.ui.navigator.ProjectExplorer">
      <includes>
        <contentExtension pattern="com.stackoverflow.commonFilter.hideFolders" /> 
      </includes>
    </viewerContentBinding>
  </extension>

</plugin>

MANIFEST.MF:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Filter_dot Plug-in
Bundle-SymbolicName: filter_dot;singleton:=true
Bundle-Version: 1.0.0
Bundle-RequiredExecutionEnvironment: J2SE-1.5
Require-Bundle: org.eclipse.ui.navigator,org.eclipse.core.resources

build.properties:

source.. = src/
output.. = bin/
bin.includes = META-INF/,\
               .,\
               plugin.xml

In the following images the "Project Explorer" displays a ".test" folder, if the filter is enabled, using the "Arrow in the top right corner > Customize View..." option, then the folder is hidden.
