Description
Steps to reproduce:
- Create a decision table with something like fooString != "" in the constraint and true in the rule cell.
- Execute the rule against a few objects.
Actual Result:
An internal Drools thread will crash with java.lang.RuntimeException: Unknown boolean operator when trying to compile fooString != "" == true.
Exception in thread "Thread-15" java.lang.RuntimeException: Unknown boolean operator at org.drools.rule.constraint.ConditionAnalyzer$AritmeticOperator.fromMvelOpCode(ConditionAnalyzer.java:1059) at org.drools.rule.constraint.ConditionAnalyzer.analyzeNode(ConditionAnalyzer.java:169) at org.drools.rule.constraint.ConditionAnalyzer.analyzeSingleCondition(ConditionAnalyzer.java:106) at org.drools.rule.constraint.ConditionAnalyzer.analyzeCondition(ConditionAnalyzer.java:99) at org.drools.rule.constraint.ConditionAnalyzer.analyzeCondition(ConditionAnalyzer.java:70) at org.drools.rule.constraint.MvelConditionEvaluator.getAnalyzedCondition(MvelConditionEvaluator.java:83) at org.drools.rule.constraint.MvelConstraint.executeJitting(MvelConstraint.java:270) at org.drools.rule.constraint.MvelConstraint.access$200(MvelConstraint.java:51) at org.drools.rule.constraint.MvelConstraint$ConditionJitter.run(MvelConstraint.java:250) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724)
Expected Result:
Even if an Exception is thrown, the currently-thrown exception is too low level and took me lots of investigation and debugging inside the drools code to figure out what I did wrong.
