Instantiation fails when database schema update is set to "drop-create"


i try to run the engine with postgres 9.5 using the newest jdbc driver “org.postgresql:postgresql:9.4.1208.jre7”.
During schema creation when the existence of certain tables is checked (namely “act_ru_execution”) the finally block inside “isTablePresent” is entered with tables equal to null. Consequently the close() operation will fail with an null pointer exception.

After the system has been started up once (setting schema creation just to “create”) subsequent execution using “drop-create” work as expected.

With h2 “drop-create” works fine.

Any ideas how to fix that without introducing a if(tables != null) tables.close()

Thank you
