Unable to catch and properly handle timeout acquiring connection from pool exception

[rjbaucells]

I need to catch and properly handle ClientException when trying to acquire connection from the pool and failing due to timeout.

The code throwing the ClientException instance does not specify a code that can be used to differentiate the exception from other ClientException instances:

    throw new ClientException(
        "Unable to acquire connection from the pool within configured maximum time of " +
        settings.connectionAcquisitionTimeout() + "ms" );

Is it possible to add a new ClientError classification code specific to this case?
