Himanshu Gahlaut commented on LENS-461:
---------------------------------------
Since LensServices class is singleton, it appears to be a big bottle neck in
running unit test cases in parallel. It will be helpful if every unit test case
which requires running in isolation in parallel is able to create an instance
of LensServices with only required initialization and services for itself.

> We have added several static singleton variables. These make it tough to
> write tests which can be run in isolation. The scope of this task is to
> identify and possibly fix statics.
