Upgrade to Jackrabbit 2.16.2

Using Hippo Jackrabbit 2.16.2-h1 now requires one specific change in  org.hippoecm.repository.jackrabbit.HippoLockManager for CMS < v13: the constructor super() call to the Jackrabbit LockManagerImpl it extends should pass in a null value for the ScheduledExecutorService parameter.

Based on this parameter being passed in as null or the actual value, the patched LockManagerImpl will conditionally retain the earlier 'just-in-time' cleanup of expired locks (CMS < v13), or restore the original Jackrabbit LockManagerImpl behavior (CMS v13+) using a scheduled TimeoutHandler to do the cleanup.

This change and conditional behavior is needed as result of REPO-1900 which removed the 'just-in-time' custom behavior for CMS v13.

See for more details the patch commited for REPO-1900
