It looks like this is because the SM.serialVersion value was null.
We can fix this in Morpho by using a real value, but Metacat should also handle the case where it is not provided.

Two pronged approach to this:
-updated Metacat's MN.update() implementation to set the SM.serialVersion to default value if it is not provided. (MN.create() had already been setting the default)
-updated Morpho to set SM.serialVersion if it is not set before calling either MN.create() or MN.update().
