>         Environment: java 7u45 and later

>
> 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.
