Currently there seem to be two (with the unused registry stuff 3, if it is still valid ?) approaches to find the 'JRE'  location  (should this better be named image location?)  -  using the launcher exe location  and using the location of the libjli shared lib.
Unfortunately those approaches are not well supported by JLI-traces , this is what the change is about.
We could probably adjust/reduce the added tracing code but I would like to know a bit more about the concerns raised.
