    Fix Version/s: felix-1.6.0

> Empty bundle.state file produces NPE
> ------------------------------------
>                 Key: FELIX-902
>                 URL: https://issues.apache.org/jira/browse/FELIX-902
>             Project: Felix
>          Issue Type: Bug
>          Components: Framework
>    Affects Versions: felix-1.0.4
>            Reporter: Pavel Tiunov
>            Assignee: Richard S. Hall
>            Priority: Critical
>             Fix For: felix-1.6.0
> If I have empty bundle.state file in Felix cache then exception is thrown while bundle
> java.lang.NullPointerException
>             at org.apache.felix.framework.cache.BundleArchive.getPersistentState(BundleArchive.java:315)
>             at org.apache.felix.framework.Felix.start(Felix.java:776)
> But if i delete bundle.state then no exception is thrown and org.apache.felix.framework.cache.BundleArchive#getPersistentState
returns 'Installed' state.
> The exception is thrown because string comparsions in org.apache.felix.framework.cache.BundleArchive#getPersistentState
do not respect java.io.BufferedReader#readLine's null return value if file is empty. Also
there is a bug in org.apache.felix.framework.cache.BundleArchive#setPersistentState that can
produce not persistent state of cache by creation of empty bundle.state file.
