Hi.
I found what may be a bug when a service name has a digit (0-9) in it.
The following exception is thrown when a client service looks up the
service.

org.osgi.framework.BundleException: Activator start error.

org.osgi.framework.InvalidSyntaxException: expected =|~=|>=|<=

It seems to emanant from Parser.java and in particular, the following
lines:
if (op == NOOP)
{
   String oplist = "=|~=|>=|<=";
   throw new ParseException("expected " + oplist);
}

What seems to be happening if the char is not a letter of the alphabet
it assumes it must be an operator. 

This happens with the following client code.

public class Activator implements BundleActivator
{
   /**
    * Implements BundleActivator.start().
    *
    * @param context the framework context for the bundle.
    */
   public void start( BundleContext context ) throws Exception
   {
       System.out.println("Before reference");
       // Query for all service references matching any language.
       System.out.println("Class name is " + P2PS.class.getName());
       ServiceReference[] refs =
           context.getServiceReferences(P2PS.class.getName(),
                                        "(P2PS=*)" );
       System.out.println("Got past reference");
       // Query for all service references matching any language.
       if ( refs != null )
       {
           // First, get a dictionary service and then check if the
word is correct.
           P2PS p2ps = ( P2PS ) context.getService( refs[0] );

           p2ps.testP2PS();

           // Unget the dictionary service.
           context.ungetService( refs[0] );
       }
       else
       {
           throw new RuntimeException( "I need a service to test it
properly." );
