well here is a thing i am sure you have thought about it but might as well state the obvious.

1) since you notice a relationship between java proccess and locked oracle procecess.

i would do the following in prouction code.

1) for every call to the db set a timeout for that session.
2) put into effect a cleanup routine so if any connections get cut or bomb out you will not have ghost processes hanging around keeping a table locked.
3) run some kinda sql query on the db via cron or other mechignisim that looks for this condition prior to it becomeing a problem.

as far as tracking down this problem.

your programmers will have to figure out which java app is makeing the offending call to the rows.

i can only assume the occurances are random but the condition is the same.
