What steps will reproduce the problem?

Inside our BootStrap.groovy:
  def init = { servletContext ->
    ...
    def configMap = new StringMap(false)
    configMap.put(FelixConstants.EMBEDDED_EXECUTION_PROP, "true")
    configMap.put(Constants.FRAMEWORK_SYSTEMPACKAGES,
		  "org.osgi.util.tracker; version=1.3.2," +
		  "javax.swing.border;," +
		  "javax.swing.event;," +
		  "javax.swing.table;," +
		  "javax.swing.tree;," +
		  "javax.naming;," +
		  "javax.naming.spi;," +
		  "javax.net;," +
		  "javax.net.ssl;," +
		  "javax.sql;," +
		  "javax.swing;," +
		  "javax.xml.parsers;," +
		  "javax.xml.namespace;," +
		  "javax.xml.xpath;," +
		  "javax.servlet.http;," +
		  "javax.security.auth.x500;," +
		  "javax.servlet;," +
		  "org.w3c.dom;," +
		  "org.xml.sax;," +
		  "org.xml.sax.helpers;," +
		  "net.sf.json;," +
		  "org.osgi.framework; version=1.4.0," +
		  "org.osgi.service.packageadmin; version=1.2.0," +
		  "org.osgi.service.startlevel; version=1.1.0," +
		  "org.osgi.service.url; version=1.0.0," +
          	  "javax.xml.transform," +
    		  "javax.xml.transform.dom," +
    		  "javax.xml.transform.stream,"        
    );

    def bundles = 
      ...
      this.getClass().getClassLoader().getResource(BUNDLE_LOCATION +
"org.modulefusion.dirinstaller.jar").toString()
  
    configMap.put(AutoActivator.AUTO_START_PROP + ".1", bundles)
    configMap.put("dirinstaller.dir", LISTENER_DIR)

    List list = new ArrayList()
    list.add(new AutoActivator(configMap))

    ...
    Felix felix = new Felix(configMap, list)
    felix.start();
    ...
  }


What is the expected output? What do you see instead?
Expected: bundles are loaded once and only attempt to reload if new or
changed bundle
Observed: DirInstaller attempts to reload all the bundles every 2-3 seconds
resulting in "Bundle symbolic name and version are not unique." exceptions

What version of the product are you using? On what operating system?
Product Version: 1.0.2
OS: Windows XP Pro SP2

Please provide any additional information below.

The error message "Bundle symbolic name and version are not unique." indicates that
DirInstaller tries to install the bundles repeatedly. To find out if a bundle should
be get installed or updated, DirInstaller compares the path to the bundle file in the
filesystem with the bundle.getLocation() of all installed bundles. It seems that
something in your setup confuses DirInstaller.

- Can you post the console output?
- Is there something special in your filesystem layout?

AH HA!  OK, the problem was that we initially loaded the bundle from the lib
directory but had the dirInstaller polling from a bundles directory.  Sorry about
that.   

Now, I'm curious why we _don't_ see these errors on our Macs

Here's some of the output:

The bundles in the configured directory actually do get installed...but, it appears
that DirInstaller keeps trying to install (not just update either).

Does this still happen with the latest version?
