> Key: AMQ-8613
> URL: https://issues.apache.org/jira/browse/AMQ-8613
> Project: ActiveMQ
> Issue Type: Improvement
> 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 10m
> 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.
