> Key: ARTEMIS-2095
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2095
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.6.3
> Reporter: Michael Andre Pearce
> Assignee: Michael Andre Pearce
> Priority: Major
> Fix For: 2.7.0, 2.6.4
>
>
> Whilst TypedProperties is meant to have a single thread acting on it (and
> this is the most typical interaction), there are occurrences where, it can be
> acted on by other threads, when this occurs some concurrent modification
> errors can occur.
> As such TypedProperties must be thread safe, but concurrency tuning should
> factor in to be most performant for single thread.
