Stephan Ewen commented on FLINK-3328:
-------------------------------------
That's all right.
We would not shade/bundle if we did not need to. The libraries we shade are
simply frequently conflicting with different version used by users, that's why
we need to make them disappear.
There is simply no good way in Java currently to allow different versions of a
library to co-exist. For everyone to always use the newest one, libraries would
have to be perfectly backwards compatible, which most are not.
Hence the ugly shading business...

> There are apparently some dependencies shaded into {{flink-runtime}} fat jar
