[ https://jira.jboss.org/jira/browse/JBTM-295?page=com.atlassian.jira.plugi... ] Andrew Dinn closed JBTM-295. ---------------------------- Resolution: Done The following classes have been modifed either to remove the finalize method or to remove redundant assignments of null to object type fields. In cases where implementtaion sin a super and subclass both logged a debug message the responsibility for logging has been devolved to the parent class with a type name included in the debug message. Mostly, these deletions will be transparent to user subclasses. For the most part they merely elide redundant code which was setting fields to null. This does not change the class signature and will only affect code which relies upon the value of inherited fields (since it is at liberty to read these before calling the super method this has little significance). However, in a very small number of cases deletion of the finalize call has caused small changes to behaviour: i) the implementation of finalize in several subclasses of StateManager failed to invoke super.finalize() which, in certain circumstances, may call method cleanup(). Deletion of the finalize method on these classes has, therefore, reinstated invocaton of Statemanager.finalize() and, possibly, cleanup() where they were not previously invoked. This was the original desired behaviour and the failure to execute this code is regarded as a bug. ii) ServerTopLevelAction used to call tidyUp() which is also called by its parent class finalize method. This will now only get called once per instance during finalization. iii) SimpleList and HashList no longer call, respectively, pop() (in a loop) or clear() to delete all entries in the list/table.
