> (Originally reported as JCR-4046, but moved to Oak as a result of introducing the OakEventFilter
in OAK-5013. From the original description: )
> A file in JCR is represented by at least two nodes, the nt:file node and a child node
named jcr:content holding the contents of the file (and metadata).
> This has the consequence that if the contents of a file changes, a change event of the
jcr:content node is reported - but not of the nt:file node.
> This makes creating listeners listening for changes in files complicated, as you can't
use the file name to filter  - especially with glob patterns (see JCR-4044 - now OAK-5019)
this becomes troublesome.
> In addition, whenever you get a change for a jcr:content node, you have to check if the
parent is a nt:file node and decide based on the result.
> It would be great to have a flag on the JackrabbitEventFilter to enable smarter reporting
just for nt:files: if a property on jcr:content is changed, a change to the nt:file node is
reported.
