About Transaction Managers Propagation Support only, features, settings, started

amy

Dear Members

Here Interface TransactionDefinition

Has this information

Note that isolation level and timeout settings will not get applied unless an actual new transaction gets started. As only PROPAGATION_REQUIRED, PROPAGATION_REQUIRES_NEW and PROPAGATION_NESTED can cause that, it usually doesn't make sense to specify those settings in other cases. Furthermore, be aware that not all transaction managers will support those advanced features and thus might throw corresponding exceptions when given non-default values.

I saw even in section 10. Transaction Management but I cant find solution for the follow

About the bold part, explicitly which Transactions managers will not support these features? and why?

Thanks in advanced
