I´m not too sure whether I understand the concept of PROPAGATION_REQUIRED
Classic definition says “execute within a current transaction, create a new transaction if none exists"
Imagine I define businessMethodA() in class A and businessMethodB() in class B both as PROPAGATION_REQUIRED
Some day a developer makes a call from A.businessMethodA() to B.businessMethodB(), should I guess after B method completes a commit would be issued? Or better, does Spring recognize the sorrounding transaction of businessMethodA() and stops the commit until this method finishes?
Let's consider the following sequence:
1) A.businessMethodA() starts
2) A calls B so B.businessMethodB() starts
3) B.businessMethodB() ends
4) A.businessMethodA() fails
A rollback is issued but until which demarcation? Start of 4) or start of 1)?
