Pavel I see

String contextPath = contextPathEl == null ? null : project.evaluator
().evaluate (Util.findText (contextPathEl));

Now I am not sure if <context-path> can be empty or not. Note that
<context-path></context-path> counts as empty, I think, since there
are no nested text nodes.

If yes, you need to check for null in findText here. If no, someone is
apparently writing it as empty, so you need to find out who that is
and fix it.
