Michael Schmeißer commented on SPARK-650:
-----------------------------------------
Please see my comment from 05/Dec/16 12:39 and the following discussion - we
are kind of going in circles here. I tried to explain the (real) problems we
were facing as good as I can and which solution we applied to them and why
other solutions have been dismissed. The fact is: There are numerous people
here who seem to have the same issues and are glad to apply the workaround
because "using the singleton" doesn't seem to provide a solution to them
either. Probably we all don't understand how to do this but then again there
seems to be something missing - at least documentation, doesn't it? What I can
tell you in addition is that we have concerned experienced developers with the
topic who have used quite a few singletons.
