Dominik Süß commented on SLING-5457:
------------------------------------
Issue reappeared randomly on some automated install tests - from looking at the
code base it looks like the osgi installer doesn't take into account that the
framework expects the bundle to be stopped and not stopping when updating. The
stop command directly before executing the update command might not have
enough time to stop the bundle. I therefore would also vote for retrying
multiple times and logging an ERROR when this does not resolve the issue. The
fact that this is only logged as INFO did hide the existence of an issue and
might lead to subtle effects when the failed bundles where not bumping the
major version.

> I don't know for what reason the Felix.updateBundle() failed (see also
> FELIX-5138 to get some more information in this case), but from my point of
> view there should be a dedicated error handling just for the
> {code}BundleImpl.update{code} call. Does it make sense to retry the
> installation at a later point in time (maybe 3 times at max)?
> (I got this exception when I deployed a large number of bundles through the
> JCR installer. It happens only once in a while, but it's an annoying task to
> fix it manually.)
