If an instance of a Throwable that is not an Exception is thrown (e.g. StackOverflowError during deletion of a huge process instance - deleteCascade is recursive), then when the command context is closed

• the engine will not properly catch this error, cf. [1]
• the engine will close the command context, cf. [2]
• the engine will flush all sessions, including the db entity manager, cf. [3]
• the db entity manager will make SQL statements
• the transaction will be committed, not rolled back

As a result, the database is in an inconsistent state.
