Nageshwar Kunichetty updated JBRULES-1173:
------------------------------------------

    Workaround Description: 
So I had the following change in file "TupleIndexHashTable.java" and it was working  :

public Entry[] toArray() {
       Entry[] result = new Entry[this.factSize];
            int index = 0;
        System.out.println("this.table.length=" + this.table.length); 
        for ( int i = 0; i < this.table.length; i++ ) {
        	FieldIndexEntry fieldIndexEntry = (FieldIndexEntry)this.table[i];
            while ( fieldIndexEntry != null ) {
                Entry entry = fieldIndexEntry.getFirst();
                //while ( entry != null){
               while ( entry != null && index<result.length) {
                    result[index++] = entry;
                    entry = entry.getNext();
                }       
                fieldIndexEntry  = ( FieldIndexEntry ) fieldIndexEntry.getNext();
            }
        }
        return result;
    }

That is, in  innner while loop I added extra codition ("index<result.length") of  "while ( entry != null && index<result.length) {".
Fix  worked for me. I am not sure if this is already fixed. 
Some I was wondering if it is fixed could I know the fixed release version/patch?

Thanks.

It was wrong piece of code pasted I have corrected it. Only fix I did was following :

I will send the test case tomorrow.
