title: Why is my Karaf OSGI bundle marked UNSATISFIED, when all references are satisfied?
body: <p>Karaf is showing my bundle as being UNSATISFIED despite all the references being satisfied.</p>
  
  <p>I am using the following three components - relevant console output from scr:list:</p>
  
  <pre><code>[20  ] [UNSATISFIED     ] com.barchart.news.modules.mysql.MySQLIndex
  [16  ] [ACTIVE          ] com.barchart.news.server.pipeline.StoryPipeline
  [14  ] [ACTIVE          ] com.barchart.news.server.common.SharedExecutorProvider
  </code></pre>
  
  <p>Components 16 and 14 provide the following services (output from service:list):</p>
  
  <pre><code>service:list com.barchart.news.server.pipeline.PipelineService
  [com.barchart.news.server.common.ModuleStatus, com.barchart.news.server.pipeline.PipelineService]
  -------------------------------------------------------------------------------------------------
   component.name = com.barchart.news.server.pipeline.StoryPipeline
   component.id = 16
   service.id = 348
  Provided by : 
   barchart-news-server (102)
  
  service:list com.barchart.news.server.common.SharedExecutorService 
  [com.barchart.news.server.common.ModuleStatus, com.barchart.news.server.common.SharedExecutorService]
  -----------------------------------------------------------------------------------------------------
   component.name = com.barchart.news.server.common.SharedExecutorProvider
   component.id = 14
   service.id = 346
  Provided by : 
   barchart-news-server (102)
  Used by: 
   barchart-news-server (102)
  </code></pre>
  
  <p>Within the barchart-news-server bundle that these both are part of, references are satisfied and bound as expected (output from scr:details):</p>
  
  <pre><code>scr:details com.barchart.news.server.pipeline.StoryPipeline
  Component Details
    Name                : com.barchart.news.server.pipeline.StoryPipeline
    State               : ACTIVE
  References
    Reference           : com.barchart.news.server.common.SharedExecutorService/*
      State             : satisfied
      Multiple          : single
      Optional          : mandatory
      Policy            : static
      Service Reference : Bound Service ID 346 (com.barchart.news.server.common.SharedExecutorProvider)
  </code></pre>
  
  <p>However, in the component from the second bundle (#20) that depends on these services, although Karaf marks the references as "satisfied", it does not bind them and activate the component:</p>
  
  <p>scr:details for com.barchart.news.modules.mysql.MySQLIndex:</p>
  
  <pre><code>Component Details
    Name                : com.barchart.news.modules.mysql.MySQLIndex
    State               : UNSATISFIED
  References
    Reference           : com.barchart.news.server.common.SharedExecutorService/*
      State             : satisfied
      Multiple          : single
      Optional          : mandatory
      Policy            : static
      Service Reference : No Services bound
    Reference           : com.barchart.news.server.pipeline.PipelineService/*
      State             : satisfied
      Multiple          : single
      Optional          : mandatory
      Policy            : static
      Service Reference : No Services bound
  </code></pre>
  
  <p>What is preventing the MySQLIndex bundle from being activated?</p>
