>          Components: JMS client
>    Affects Versions: 5.17.1
>            Reporter: Enrico Olivelli
>            Assignee: Jean-Baptiste Onofré
>            Priority: Major
>             Fix For: 5.18.0, 5.17.2

>          Time Spent: 1h
>  Remaining Estimate: 0h

> Currently when you create a selector with OR and ANDs the filter creates a huge stack trace.
> This is because for each element in the OR and AND expression node we have to execute a method call.
> This is happening because OR and AND expressions are treated as BinaryExpressions.
> A very simple but effecting improvement is to not represent OR and AND expressions as binary expression but store the list of siblings expression in only one node.
