[rules-users] get new errors caused by KnowledgeBuilder.add()

Hi, I have rules (drl format strings) stored in a database column in a schema like MyRules(rule_id integer, name text, rule text, enabled boolean ... ) I query the db to get them and iterate over the rows and add using KnowledgeBuilder.add() using String.getBytes. (I dont want to move to guvnor as of now) some rules might have compilation errors, hence the KnowledgeBuilder.hasErrors() is set to true. those will not be added to the package by the PackageBuilder. My problem is to log the error causing rule_id and the error message. KnowledgeBuilderErrors dosent expose the internal errors list so that I could see if any new errors are in the arraylist from the last time error seen time and log them. But only solution i could think of is using the low level api of using DrlParser to pre-parse it to check for errors+log and add to the kBuilder if its not failed. is there any elegant way to do this? I am using drools-5.2.0.final -- Regards, Sandeep Bandela.
