             Summary: Error when when fragment bundle is updated
                 Key: FELIX-3714
                 URL: https://issues.apache.org/jira/browse/FELIX-3714
             Project: Felix
          Issue Type: Bug
          Components: File Install
    Affects Versions: fileinstall-3.2.6
            Reporter: Evgeniy Sedyshev


On our project we have FileInstall watching a directory with bundles. One of those bundles is a fragment. 
When the fragment is modified (or deleted/created), we get the following error in the log:

2012-10-17-13:20:53.406+0400 ERROR [Thread-17] org.apache.felix.fileinstall    In main loop, we have serious trouble
java.lang.NullPointerException: null
        at org.apache.felix.fileinstall.internal.DirectoryWatcher.findBundlesWithFragmentsToRefresh(DirectoryWatcher.java:1273) ~[na:na]
        at org.apache.felix.fileinstall.internal.DirectoryWatcher.process(DirectoryWatcher.java:491) ~[na:na]
        at org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:291) ~[na:na]

And what is more critical none of the other modified bundles becomes updated.

The source of the NPE is 
if (hostBundle.getSymbolicName().equals(path.getName()))  
because there is no check here for SymbolicName being null.

In our case the problem was in that there was a non-bundle jar inside osgi container that therefore didn't have a SymbolicName, so we just removed it and that solved the problem. 

However, I strongly believe that there should be a check for not null in the mentioned line.
