Throw early on null tablePrx #72

Closed joshmoore closed 4 years ago

joshmoore commented 5 years ago

An error in the OMERO.tables implementation returned null proxies. The TableCloser happily took the null leading all subsequent methods to fail (e.g. initialize()). Rather than checking in each method, null proxies are disallowed.

cf. https://merge-ci.openmicroscopy.org/jenkins/job/OMERO-test-integration/171/testngreports/integration/TableTest/createTable/

Exception Ice.UnknownException
Message: (none)

Getting this in as a straight-forward null check (that's been in for quite some time).
