I'm working with MySQL and I have 2 transaction, one is within the other.
External:
Inner transaction:
Class-helper, that works with Hibernate-transactions:
The inner transaction is committed. But when the external transaction is tried to be committed, we wait 100 seconds(this is configured in configuration of MySQL), then the exception is thrown. Here is the log that contains the error:

Maybe someone can help me? I don't even know the source of the problem...

My TransactionManager has field "nextedTransactionAllowed". But when I set it "true", nothing changes.

The problem was not about nested transactions. Some operation with database were simply performed in other connection.
