> Track connection proxies in the transaction

> Key: TOMEE-2257
> URL: https://issues.apache.org/jira/browse/TOMEE-2257
> Project: TomEE
> Issue Type: Improvement
> Reporter: Jonathan Gallimore
> Assignee: Jonathan Gallimore
> Priority: Major
> Fix For: 7.0.6
>
>
> Under load, it is possible for connection proxies to be cleaned up while they
> are still associated with a transaction. The result is that the connection
> resources are closed as the AutoConnectionTracker cleans up, and the
> connection associated with the transaction is returned to the pool, thus
> failing next time it is used.
> The change proposed does the following:
> * Maintains a reference to the proxy for the duration of the transaction to
> prevent it being cleared up
> * When detecting abandoned connections, clearly log these at WARN level,
> allowing the developer to inspect their code and fix any leaks
> * allow the destruction of proxies to be turned off (this does not turn off
> the logging)
> * provide a test to ensure connections aren't aggressively cleaned up when
> there is a lot of GC
> * provide tests to make sure abandoned connections are clearly logged
