[rules-users] Help with MR3

[s erel]

I've done a little debugging. The code fails in the following segment:

public static class HashTableIterator
...
 while ( this.entry == null ) {
                    this.row++;
                    if ( this.row == this.length ) {
                        return null;
                    }
                    this.entry = this.table[this.row]; *// ---> index out of
bounds exception*
                }
}

this.row has the same value as this.length despite the condition above it.
Probably a race condition issue.
