             Summary: Improve parsing timings
                 Key: JEXL-389
                 URL: https://issues.apache.org/jira/browse/JEXL-389
             Project: Commons JEXL
          Issue Type: Improvement
            Reporter: Dmitri Blinov


There seems to be a known and old issue with javacc with respect to creation of 
LookaheadSuccess exception instance inside parser class, which hits the 
performance if parsing is intensively used and many Parser objects are created. 

More details and suggested fixing approach can be looked at 
https://issues.apache.org/jira/browse/SOLR-11242

I think we can adopt the fix until it will be fixed in javacc.
