[ https://issues.jboss.org/browse/DROOLS-319?page=com.atlassian.jira.plugin... ] David Tombs updated DROOLS-319: ------------------------------- 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}}. {noformat} 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) {noformat} 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. was: 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.
