+1 . It's not widely used and is yet another reason for unpredictability.
I don't understand this effort.
With
https://bugzilla.redhat.com/show_bug.cgi?id=1098508 in mind - why to abandon it?
I'm not exactly against this proposal, but I still have an feeling that there is
underlying issue in java packages or in jtools.
The correct approach, if jre + sdk separation will be kept, should be:
only jre installed - use jre
sdk installed (jre installed as dependence) :
- application requires jre - use jre
- application rewires devel, use jdk
Now - jdk9 ... is different. Maybe something can be done better so jtools nor java apps
suffer by above logic.
