I've built rules using DSL's before and with 5.3 I am seeing Eclipse hang intermitently during builds. I've seen this in previous versions of DROOLS so wondered what/where is the most stable version of DROOLS? I downloaded, but have not yet installed the product version (this is for a lartge US firm, so buying the product is feasible). They could not accept needing to kill off processes when they build. The schedule is VERY tight so I am asking this question while I install the product version (5.2). The rules, XOM, and DSL are simple, so I think the parser is intermitently generating some infinitely deep tree during builds. -- View this message in context: http://drools.46999.n3.nabble.com/DSL-translation-handing-what-is-the-mos...
