  <p>From the line Reason: Missing Constraint: Bundle-RequiredExecutionEnvironment: CDC-1.0/Foundation-1.0,J2SE-1.3, my understanding is that it has some sort of version conflict with J2SE, but the log correctly shows my current java version so I am not sure what the issue is at all.</p>
  
  <p>Assistance would be appreciated.</p>
