Richard S. Hall commented on FELIX-4528:
----------------------------------------
I understand your argument, but this was precisely the reason why we always
tried to keep launching issues separate from the framework implementation, so
that we don't need to insert any n-line changes for arbitrary launching
purposes since everyone always views their own launching use case as more of a
requirement than someone else's.
At a minimum, this seems like you should be proposing a feature request against
Main, which is the launcher, as opposed to the framework implementation. Even
then, we've still largely maintained that Main was more of a simple, general
purpose launcher and not meant to handle all cases.
Yet another approach is to simply create a new Felix subproject for a
JNLP-specific launcher that has all the bells and whistles necessary to easily
use the Felix framework within JNLP.

>
> Unsigned JNLP files are required for most real world cases - especially those
> with dynamic deployment needs where the host URL cannot be known in advance.
> To use System properties in unsigned JNLP files they must be prefixed with
> "jnlp." - which effectively renders all current Felix properties unusable.
> Attached is a patch with one implementation approach for this - a mod to
> SecureAction to check for a "jnlp," version of a property before falling back
> to System properties or the supplied default.
> An alternative would be additional init code in Felix or FelixConstants to
> test each property that we wish to expose to JNLP files and push any non-null
> value into System properties. This would be more transparent, but also more
> maintenance whenever new FelixConstants are added.
