FWIW, the LRUCache is also used in
`org.apache.activemq.artemis.core.protocol.openwire.OpenWireProtocolManager`

> Project: ActiveMQ Artemis

> 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.
