Hi All,

I tried to migrate Drools 2.1 to 4.0.7 using SpreadsheetCompiler. 

What do these numbers mean in following exception?

org.drools.rule.InvalidRulePackage: [9,18]: unknown:9:18 mismatched token: [@44,188:188='.',<8>,9:18]; expecting type THEN[20,18]: unknown:20:18 mismatched token: [@90,402:402='.',<8>,20:18]; expecting type THEN[31,18]: unknown:31:18 mismatched token: [@136,606:606='.',<8>,31:18]; …

Thanks,

Hong
