Literally hundreds of exceptions reported on standard error (I think they might have been suppressed before because all but IOExceptions were silently discarded somewhere). > On languagetool.org the problem seems network-related, there's no > crash but the server hangs.

Maybe there will be some crash or hanging after all. The hanging might have been caused by the double-lock anti-pattern. By the way, we really need to cache the rules. Loading XML rules takes a lot of time (I'm profiling at the same time).
