> ------------------------------------
>

> URL: https://issues.apache.org/jira/browse/ARTEMIS-2017
> Project: ActiveMQ Artemis

> Reporter: Justin Bertram
> Assignee: Justin Bertram
> Priority: Major
> Fix For: 2.7.0, 2.6.3
>
>
> Concurrent usage of {{SelectorParser.parse()}} can cause the {{cache}} to
> grow past its hard-coded size of 100. Synchronizing {{put}} operations
> eliminates this problem.
