RedHat advised "Upgrade to JDK11+, where the finalize method is deprecated and implemented as a no-op, and memory is released when the object becomes unreachable." ( https://access.redhat.com/solutions/6724981, subscription required) We did and it solved our problem. Since then we've also used OpenJDK 11 with Tomcat 9.0.*. -- "Hell hath no limits, nor is circumscrib'd In one self-place; but where we are is hell, And where hell is, there must we ever be" --Christopher Marlowe, *Doctor Faustus* (v. 111-13)
