>
> For cas pools, getCas returns a handle to the InitialView of an empty CAS,
> and stores this handle to match in releaseCas. This breaks for services that
> employ sofamapping. The empty CAS is filled from a serialized CAS sent to the
> service. It is possible that a CAS received may not contain the view,
> CAS.NAME_DEFAULT_SOFA, specified by sofamapping.
> Then, when the service tries to return the CAS to the pool, releaseCas blows
> up at the first line,
> CAS cas = aCas.getView(CAS.NAME_DEFAULT_SOFA);
> so the CAS is not returned to the pool ==> CAS leak.
> The cas pool should be storing references to the base CAS, which is
> independent of views.
