Re: [rules-users] Memory leak in 5.2/5.3

as suggested in his post by Thomas , we are retracting the facts from memory. we are doing it in the finally block to make sure a rule session exception does not leave the facts in memory . for ex, we came across an incorrect regular expression syntax within the rules when using incorrect syntax . java.util.regex.PatternSyntaxException: Illegal character range near index 7 ^[A-Za-Z]+ retracting the facts in finally block fixes the leak . That, besides making sure we are reusing the StatefulSession rather than creating a new one every time. -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Memory-leak-in-5-2-5-3-tp32...
