Alan Paxton 2296c624fa Perform java static checks in CI (#11221)
Summary:
Integrate pmd on the Java API to catch and report common Java coding problems; fix or suppress a basic set of PMD checks.

Link pmd into java build / CI

Add a pmd dependency to maven
Add a jpmd target to Makefile which runs pmd
Add a workflow to Circle CI which runs pmd
Configure an initial default pmd for CI

Repair lots of very simple PMD reports generated when we apply pmd-rules.xml

Repair or exception for PMD rules in the CloseResource category, which finds unclosed AutoCloseable resources.
We special-case the configuration of CloseResource and use the // NOPMD comment in source the avoid reports where we are the API creating an AutoCloseable, and therefore returning an unclosed resource is correct behaviour.
