---------------------------------------
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)

org.apache.felix.fileinstall.internal.DirectoryWatcher.process(DirectoryWatcher.java:491)

org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:291)

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.
