> Doing some performance tests I notice that even if no VariableResolver /
> PropertyResolver is set, when resolving EL expressions the code goes directly
> through that path, doing some unnecessary operations or calling some
> specified ELResolvers more than once.
> To prevent that, we can check if it was installed a custom VariableResolver /
> PropertyResolver and if it is not found, let the EL chain to continue its
> route. For example, DefaultPropertyResolver has an extra call to
> FacesContext.getCurrentInstance() and with this code, we prevent that call.
