Dmitri Blinov updated JEXL-216:
-------------------------------
    Description: At the moment the {{Engine.parse()}} method synchronizes on {{parser}} member even if the caching is enabled and the actual parsing is not required, in case of cache hit. This effectively serializes processing of scripts and expressions in multithreaded scenario. The suggestion is to separate synchronization on cache from synchronization on parser, with the latter only being performed if actual parsing is required.  (was: At the moment the {{Engine.parse()}} method synchronizes on parser member even if the caching is enabled and the actual parsing is not required, in case of cache hit. This effectively serializes processing of scripts and expressions in multithreaded scenario. The suggestion is to separate synchronization on cache from synchronization on parser, with the latter only being performed if actual parsing is required.)
