Yes. CarbonContext.getCurrentContext() method is deprecated and therefore
we should avoid using that. This is noticed in 4.2.0 [1] and it is fixed in
4.2.1 [2] component. I have created a feature for this new version as well
[3]. As mentioned in other thread [4], I did not continue fixing the code
in 4.2.1 as we would need a Stratos Deployment to test those.

Yes. The product should use 4.2.1 feature if there are issues due to
CarbonContext. I'm not sure about the installation failure during
p2-profile-gen.

I will further check on this.
I'm sorry for the inconvenience.
