Fwd: Enforce noninstantiability with a private constructor

[Rishi Solanki <ri...@gmail.com>]

Moving thread to dev list.

All, we have started effort on this under OFBIZ-7272. In that effort we
found some classes isn't in use. Once completed this effort we will share
them for discussion so that we can decide weather to keep them in OFBiz or
we are good to remove them.

Taher,

Thank you very much for your inputs. I was thinking to do the same to add
private constructors first then do other things. But after your reply I
think better to pick one class at a time, and check everything for that
class which includes removing public modifiers, method and fields. Marking
classes members as final and all your suggestions.

We would start picking classes one by one, and check all its references and
finally make necessary changes for each class. In that way we would be able
to match the classes with purpose. This is better way to fix this design
flaw.

Thanks!

Team,

We have started pushing changes into trunk, in case anyone would like to
review then we are keeping it very simple;
- For any class we have an sub ticket with class name.
- On the ticket description we are posting the changes needs to be done,
then discuss and finalize the changes.
- Upload the patch with same finalized changes and edit the ticket's
description accordingly.

If you would like to review, then commit, patch and ticket description all
are same so that can be reviewed easily. Thanks!
