NullPointerException during resolveBundles
------------------------------------------

                 Key: FELIX-768
                 URL: https://issues.apache.org/jira/browse/FELIX-768
             Project: Felix
          Issue Type: Bug
          Components: Framework
    Affects Versions: felix-1.2.1

            Reporter: Carsten Ziegeler


we are experiencing very sporadic NPEs with 1.2.1 in the Felix class
(see stack trace below). This happens during a series of bundle installs
and starts (intercepted by resolveBundles and refreshPackages) calls.
While our implementation is not optimal (which we fixed now), it seems
that this is a very rare race condition.
