title: Eclipse User Library reports existing jar as 'missing'
body: <p><strong>Eclipse Indigo</strong></p>
  
  <p>I use user libraries to manage sets of dependencies for my builds in eclipse.</p>
  
  <p>To this point it's been very straight forward, however today I had a new jar dependency I needed to add to a user library. I clicked Add Jar in the User Library page and located the jar in my file system. It appears in the user library list of jars and everything looks fine.</p>
  
  <p>Then I close window and when I reopen the User Library view, that library is now in error. It reports the JAR as missing now. The only peculiar thing I noticed is it now lists the path as an incorrect absolute path instead of a relative path like other jars show. I have no way of editing this path it shows. All I can do is click to locate the jar in the file system, which it already loads up as the exact jar in the correct folder.</p>
