Errors in documentation: Transaction Core Programmers Guide

                 Key: JBTM-758
                 URL: https://jira.jboss.org/browse/JBTM-758
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Documentation
    Affects Versions: 4.11.0
            Reporter: Mauro Molinari
            Priority: Minor

I'm going to highlight some errors I found during the reading of the Transaction Core Programmers Guide (TX-PG-5/11/10):

- page 31: when describing LogManager: "The *shared* parameter only has meaning if *ot* is RECOVERABLE"; actually the two parameters are named *objectModel* and *ObjectType* respectively in the caption of the paragraph
- page 36: in the example, I think the line with "A.add(new ShutdownRecord(...)" is not pertinent
- page 64: the last sentence says that the issues described in that paragraph will be addressed in the next section, but the next section is about configuration
- page 65: the second paragraph has some typographic problem (<module>propertyManager, <name>EnvironmentBean)
- page 69: in the second paragraph: "All of the implementations are derived from the ObjectStore interface"; actually, ObjectStore is a class to extend, not an interface to implement

Lastly, an observation about the depiction of finalizers as "destructors": in this guide, the finalize method is considered a destructor. However, in Java it is not actually. Anyway, it's not clear if calling terminate() in the finalize() is mandatory or not. If so, why isn't it called directly in com.arjuna.ats.arjuna.StateManager.finalize()? If not, I have another doubt. In all the examples of user classes (i.e. page 60) the finalize() is implemented as:

public void finalize()

However, super.finalize() is not called. Isn't it risky? I mean, in this way the code in com.arjuna.ats.arjuna.StateManager.finalize() is never called... I think the documentation should be more clear on this subject.
