In FLyrVect.getFullEnvelope() I found this:

        // Esto es para cuando se crea una capa nueva con el fullExtent de ancho
        // y alto 0.
        if (rAux == null || rAux.isEmpty() || rAux.getMaximum(0) - rAux.getMinimum(0) == 0
            && rAux.getMaximum(1) - rAux.getMinimum(1) == 0) {
            try {
                rAux =
                    geomManager.createEnvelope(0, 0, 90, 90, SUBTYPES.GEOM2D);
            } catch (CreateEnvelopeException e) {
                logger.error("Error creating the envelope", e);
                e.printStackTrace();
            }
        }

So, If a vectorial layer is empty, always a returns a envelope of (0 0,90 90) . Ignoring the fact that this coordinate can be inappropriate for current View (and there's no way to know it), I think that, in this case, an empty envelope should be returned. The method which requires the full envelope must be in charge of manage this state (a empty layer).

An example of this is FLayers.getFullEnvelope() which must check it.

Also, DefaultEnvelope.add(Envelope) must check if received envelope is empty.

I don't provide a patch due to this change could produce many side effects.
