ArrayIndexOutOfBoundsException in org.drools.util.TupleIndexHashTable.toArray ----------------------------------------------------------------------------- Key: JBRULES-904 URL: http://jira.jboss.com/jira/browse/JBRULES-904 Project: JBoss Rules Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.0.0.MR3 Environment: Java 1.5 Reporter: Dirk Bergstrom Assigned To: Mark Proctor Fix For: 4.0.0.MR4 Attachments: real-testcase.tgz, testcase.tar.gz When asserting a particular object type, I get the following stacktrace: java.lang.ArrayIndexOutOfBoundsException: 26 at org.drools.util.TupleIndexHashTable.toArray(TupleIndexHashTable.java:178) at org.drools.reteoo.CollectNode.assertObject(CollectNode.java:212) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:317) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:183) at org.drools.reteoo.Rete.assertObject(Rete.java:121) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:201) at org.drools.reteoo.ReteooWorkingMemory.doAssertObject(ReteooWorkingMemory.java:70) at org.drools.common.AbstractWorkingMemory.assertObject(AbstractWorkingMemory.java:766) at org.drools.common.AbstractWorkingMemory.assertObject(AbstractWorkingMemory.java:578) at net.juniper.dash.data.DataSource.reconcileAssertedRecords(DataSource.java:250) at net.juniper.dash.data.DataSource.populateRecords(DataSource.java:193) at net.juniper.dash.Updater$DataSourceProcessor.work(Updater.java:177) at net.juniper.dash.Refresher.run(Refresher.java:69) I added some println() statements, and it's not an off-by-one error, it's something more serious. I changed the allocated size of the array to (this.size * 10), and it *still* tried to overfill the array. The hashtable had 26 entries, but it tried to add 261, and counting.
