>             Project: Tapestry 5
>          Issue Type: Bug
>          Components: plastic
>    Affects Versions: 5.3
>            Reporter: Howard M. Lewis Ship
>            Assignee: Howard M. Lewis Ship
>            Priority: Critical
>              Labels: deadlock, performance
>
> Discovered during load testing; the scenario is a cold start for the 
> application then hitting it with large numbers of concurrent requests with no 
> ramp up. The deadlocks involve two methods:
>      PlasticClassLoader.loadClass()
>      PlasticClassPool.getClassInstantiator()
> A proper solution would to make these methods share a single explicit Lock, 
> rather than be synchronized.
