[jboss-jira] [JBoss JIRA] (DROOLS-1189) Parser error doesn't point at the problematic line in case of extra double quote

Parser error doesn't point at the problematic line in case of extra double quote -------------------------------------------------------------------------------- Key: DROOLS-1189 URL: https://issues.jboss.org/browse/DROOLS-1189 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.4.0.Final Reporter: Toshiya Kobayashi Assignee: Mario Fusco Priority: Minor If you have a rule which wrongly has an extra double quote, {noformat} rule "rule1" when then System.out.println("1""); end rule "rule2" when then System.out.println("2"); end rule "rule3" when then System.out.println("3"); end {noformat} Drools raises parser errors like this: {noformat} [20,0]: [ERR 102] Line 20:0 mismatched input '' [20,0]: [ERR 102] Line 20:0 mismatched input '<eof>' in rule "rule1" [0,0]: Parser returned a null Package {noformat} It doesn't point at the problematic line which actually contains the extra double quote. So it's difficult for users to find the root cause (Imagine you have bunch of rules generated by decision table).
