[jboss-jira] [JBoss JIRA] Created: (JBRULES-2500) soundslike throws NullPointerException when one argument contains no consonants

soundslike throws NullPointerException when one argument contains no consonants ------------------------------------------------------------------------------- Key: JBRULES-2500 URL: https://jira.jboss.org/jira/browse/JBRULES-2500 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.0.1.FINAL Environment: mvel2-2.0.12 Reporter: Steve Ronderos Assignee: Mark Proctor When using soundslike, if one argument can't be handled by Soundex an Exception is thrown. My exact situation is that the 1st parameter (before the soundslike operator) resolves to a string that soundex does not support. It could be a string with only vowels, numbers and spaces. I would expect soundslike to simply return false. The stacktrace: java.lang.NullPointerException at org.drools.base.evaluators.SoundslikeEvaluatorsDefinition$StringSoundsLikeEvaluator.evaluate(SoundslikeEvaluatorsDefinition.java:148) at org.drools.rule.LiteralRestriction.isAllowed(LiteralRestriction.java:92) at org.drools.rule.LiteralConstraint.isAllowed(LiteralConstraint.java:109) at org.drools.rule.OrConstraint.__AW_isAllowed(OrConstraint.java:51) at org.drools.rule.OrConstraint.isAllowed(OrConstraint.java) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:143) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:42) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:185) at org.drools.reteoo.EntryPointNode.__AW_assertObject(EntryPointNode.java:146) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1046) at org.drools.common.AbstractWorkingMemory.__AW_insert(AbstractWorkingMemory.java:1001) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:788) at org.drools.impl.StatelessKnowledgeSessionImpl.__AW_execute(StatelessKnowledgeSessionImpl.java:259) at org.drools.impl.StatelessKnowledgeSessionImpl.execute(StatelessKnowledgeSessionImpl.java) I checked out the code and found that when soundex can not parse a string it returns null. I think this could be avoided by doing the Soundex.soundex(String) and checking for null before calling equals. I'll try to submit a patch if I have the time. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
