Stephane Chomat commented on KARAF-334:
---------------------------------------
StartLevel:
At startup the startlevel is equal to 1. And only bundles which startlevel is
one are started, the others are started in lock method when this code set the
startLebel at defaultStartLevel (default value is 100). And if you want use
scheme like mvn: or wrap: or dir: in karaf.auto.start you must start this
handlers service at level 1.
You cannot use this scheme in karaf.auto.install.x because this properties is
installed before the properties karaf.auto.start.x
To resolve the first problem (start handler bundles which provides new scheme,
at level greater than 1), I try to add this line at the end of the loop :
+ sl.setStartLevel(startLevel);
But there is a conflict with lock code. I work if you set karaf.lock to false.

> Project: Karaf
> Issue Type: Improvement
> Components: runtime
> Affects Versions: 2.1.2
> Reporter: Stephane Chomat
> Assignee: Guillaume Nodet
> Fix For: 2.1.3, 2.2.0

> At startup, Karafi does not support urls like mvn:, obr:.
> Imagine that at level 5 you install the bundle pax-url-mvn with
> karaf.auto.start.5 = "file: pax-url-mvn.jar | pax-url-mvn"
> and then at level 10 you install mvn:. ... With karaf.auto.start.10 = "mvn
> :....| ...."
> At the level 6 the url handler 'mvn' is available and you can use it.
> This feature does not work with Karaf
> I propose this path :
