Short description of error
When applying bump map to the material, the shadows are no longer smooth. they loose quality.
A workaround is to set the lights size to 1, at least. But for using HDRI, i don't know what to do..
I believe this is caused by an extreme value for bump (causing the normals to point in all kinds of directions). Or I'll quote @Brecht Van Lommel (brecht) from T54498:
In general such artifacts can happen if the normals are too different from the actual geometry, and the low poly geometry reveals itself
another quote from there:
It's another case of the terminator problem. We have some work towards improving it in D2574 but there's no easy solutions in general.
As a workaround you can lower the value of your multiply node, or better in this case use True displacement / Adaptive Subdivision, see the manual
I dare archiving this as known limitation, unless @Brecht Van Lommel (brecht) has something to add?
