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
