java: prefer errors to fatal errors

Browse Source 
Fatal errors are inconvenient, and should be reserved to cases where
we cannot continue.  Here, it could even be warnings actually: these
directives will simply be ignored.

* data/skeletons/lalr1.java: Prefer error (b4_complain) to fatal
errors (b4_fatal).
* tests/java.at (Java invalid directives): New.
