Description

With OAK-3842 a fair number of oak packages have gotten their export version reset to 0.0.0 instead of exporting a particular version (as that package is not meant to be a stable API just yet).

One consequence of this change is that JcrResourceProviderFactory now fails with a NoClassDefFoundError as it has as import dependency org.apache.jackrabbit.oak.plugins.observation; resolution:=optional; version="[2.0, 3)" while that is now exported as 0.0.0.

Not sure if we have to do much or of this gets fixed automagically when we're releasing a new jcr.resource bundle (cziegeler, wdyt?).

Here's the details of the exception:
