Very sporadic NPE during
Hi,
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.
Any ideas? Should I file a bug?
Regards
Carsten
