Ian Boston commented on SLING-1802:
-----------------------------------
Using last modified of the bundle and comparing it to the last modified of the
resource in jcr appears to be a good way of determining if an update is
required. Determining the last update of a bundle is less easy as
bundle.getLastModified() gives the time when the bundle was ast modified in the
OSGi container, not last built. The BND Tool adds a Manifest Bnd-LastModified
header which is the build time of the bundle but this isnt present in
absolutely every bundle.
So
Math.min(Math.min(Long.parseLong((String)bundle.getProperties().get("Bnd-LastModified")),bundle.getLastModified()),entryUrlConnection.getLastModified());
should give a reasonable approximation for each item and be good for future
changes to Felix, should they happen.

> Key: SLING-1802
> URL: https://issues.apache.org/jira/browse/SLING-1802
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Affects Versions: JCR ContentLoader 2.1.0
> Reporter: Ian Boston
>
> If you create an updated bundle containing content to be installed by the
> content loader, that updated content does not get installed.
> You can use overwrite:=true, however if you do that the entire tree is
> overwritten including any content from other bundles.
> A workarround is to only allow one bundle to update any one folder, although
> this may not be suitable for certain configurations.
> This was discussed at http://markmail.org/thread/t4efmodaxofofjwr
> One possible solution is to use the lastModified date of the bundle to
> determine if new content should be uploaded.
