When I build my project using 3.4.2, I get occasionally NPE errors around 40% of the time.

I think it may be related to conflicting dependencies, but I am not really certain.

I have tried reading through verbose build outputs, but it is not easy to find any authoritive answer.

Does anybody have any idea?

Of course there is no problem on 3.5.1, but our build server (and target) is 3.4.2, so we need to find out.
