Journalling (does it work?)

Hello JR users and developers!


Recently we have faced a problem with journalling that seems to resemble the one reproduced in JCR-1846 (https://issues.apache.org/jira/browse/JCR-1846). But that defect is closed and said to be fixed since 1.5.2, but we are using 1.5.5. 
 
And in relation to that I have several questions:
1) Is "journaling" recommended for production use? 
2) Is it true that "journaling" has locking issues because of only one instance of "journal" accessed by repository?
3) Is it possible to overcome the limitation we have faced and described in JCR-1846 and make journal do its job?
4) What is the logical/practical limit on the number of cluster nodes participating in "journaling"?
5) How smart or risky is it to implement our own "journaling"?

Best regards,
Andrey
