[ https://jira.jboss.org/browse/JBRULES-2574?page=com.atlassian.jira.plugin... ] Mark Proctor commented on JBRULES-2574: --------------------------------------- We initialise the row to -1, yet still do a lookup on that -1, hence the exception. {code} public FieldIndexHashTableFullIterator(final AbstractHashTable hashTable) { this.hashTable = hashTable; this.row = -1; } /* (non-Javadoc) * @see org.drools.util.Iterator#next() */ public Object next() { while ( true ) { if ( this.list == null ) { // check if there is a current bucket while ( this.list == null ) { // iterate while there is no current bucket, trying each array position this.list = (LeftTupleList) this.table[this.row]; {code} on the reset we do: {code} public void reset() { this.table = this.hashTable.getTable(); this.length = this.table.length; this.row = 0; this.list = null; this.leftTuple = null; } {code} So now it's reset to 0, which shows lack of consistency. Need to be careful though as just defaulting the constructor to 0 may incorrect behaviour. Once correct I suspect the same bug will be in RightTupleIndexHashTable. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
