Description

There is an installed blueprint.xml. (by install -s blueprint:mvn:org.abc/my-project/1.0-SNAPSHOT/xml, or deploy this blueprint.xml into deploy folder).

then, if you do feature:install xxxx, to install some other feature (no dependencies to the blueprint.xml above), the installed blueprint.xml will always be updated and restarted, that's not expected behavious.

After checking with org.apache.karaf.features.internal.service.Deployer class, I found that the old checksum will only be calculated in case of url start with "jar:" (Line 1159), so in case of the url start with "blueprint:", the new checksum will never equal with old checksum, then it will be put into deployment.toUpdate Map.

The Deployer class should be fixed for "blueprint:" deployment.
