I have a toggleable command that is defined like so:

      <command
         defaultHandler="..."
            id="toggleTest"
            name="Test">
         <state
               id="org.eclipse.ui.commands.toggleState">
            <class
                  class="org.eclipse.ui.handlers.RegistryToggleState">
               <parameter
                     name="persisted"
                     value="true">
               </parameter>
               <parameter
                     name="default"
                     value="false">
               </parameter>
            </class>
         </state>
      </command>

This works fine, and the state of the command appears (in the UI) to be persisted across application restarts.

However, when I attempt to read the state after restarting, the code fails at the assertion (with an AssertionError, not a NullPointerException) regardless of the prior state:

  Command cmd = ((ICommandService) PlatformUI.getWorkbench()
    .getService(ICommandService.class)).getCommand("toggleTest");
  assert cmd.getState(RegistryToggleState.STATE_ID).getValue() != null;


Reproducible: Always
