> Take a rule with 2 variables int the init part, like
> 		$maxCa:CompanyCA() from accumulate($ca:CompanyCA($year:year) from $p.cas, 
> 										init(ecrm.party.CompanyCA currentCA=null;int maxYear = 0;),
> 										action(maxYear = Math.max(maxYear, $year);),
> 										result(currentCA)); 
> which can return the year and the ca where the ca is max.
> It won't compile with the error that company CA is not declare.
> The bug is in the class org.drools.rule.builder.dialect.java.JavaAccumulateBuilder
> line 194
>             int index = 0;
>             for ( Iterator it = initCodeAnalysis.getLocalVariablesMap().entrySet().iterator(); it.hasNext(); ) {
>                 Map.Entry entry = (Map.Entry) it.next();
>                 attributes[index] = (String) entry.getKey();
>                 attributesTypes[index] = ((JavaLocalDeclarationDescr) entry.getValue()).getType();
>             }
> when the variables are put in the context, only the first is put (index stay at 0)
> We should increment the index
>             int index = 0;
