Finally, I looked for java libraries for Earley parsers, and found this one. Constructing the grammar was straightforward, and I had the advantage of being able to "weight" each production rule with a 1-epsilon probability, meaning it would selectively produce the shortest possible parse derivation first.

Next with some research I read Parsing With Derivatives, with an implementation in scala. Unfortunately, this still appears to have exponential runtime; my initial test target string of ~20 characters took an hour to complete.
What are some alternatives?
