So, two solutions:
1. Keep java regexp ...

is more a protection pattern than really a filter pattern, and it could
probably be hard-coded).
If it were easy to implement all java regex features in
dk.brics.automaton.RegExp, then they probably would have. Alternately,
if they'd implemented all java regex features, it probably wouldn't be
so fast. So I worry that attempts to translate are doomed. Better to
accept the differences: if you want the speed, you must use restricted
regexes.
How about:
3. Add new plugins that use dk.brics.automaton.RegExp, using different
default regex file names. Then folks can, if they choose, configure
things to use these faster regex libraries, but only if they're willing
to write the simpler regexes that it supports. If, over time, we find
that the most useful regexes are easily converted, then we could switch
the default to this.
