Description:
iterator() method throws null pointer exception when it is called but the getCapabilites request is not complete.  It should check if it is done, if not then it should wait until it is done, then process.
The line causing the exception is:
        for (int i = 0; i < capabilities.getLayers().length; i++)

It occurs when there is a map already created with WMSLayers.  
When the program is started and Local Registry/Catalog has not been loaded.  When the map is opened LayerManager calls iterator, but the getCapabilites thread is not done... so exception.  If it waited for a second woke, checked, then slept, woke, checked etc... the exception wouldn't be thrown.  If it is determined that the getCapabilities() has failed, then return an empty iterator.
