Concerns upgrading Atomikos version from 3.9.x to 6.0.0

[AhamBrahmasmi2020]

Issue:

After upgrading Atomikos version from 4.0.4 to 6.0.0, we are encountering two warnings:

Warning 1:

com.atomikos.logging.JULLogger.logWarning A JTA transaction is required but none was found - please start one first (or set localTransactionMode=true to allow JDBC transactions)

Warning 2:

WARNING [TestScheduler_Worker-2] com.atomikos.logging.JULLogger.logWarning com.atomikos.jdbc.AtomikosNonXADataSourceBean 'jdbc/MatriDBDataSource' [NB: this resource does not support two-phase commit unless configured as readOnly] WARNING [TestScheduler_Worker-2] com.atomikos.logging.JULLogger.logWarning This method needs a transaction for the calling thread and none exists. Possible causes: either you didn't start a transaction, it rolledback due to timeout, or it was committed already. ACTIONS: You can try one of the following:

Make sure you started a transaction for the thread. Make sure you didn't terminate it yet. Increase the transaction timeout to avoid automatic rollback of long transactions; Environment:

Spring Hibernate application NonXA transaction Are these warnings expected behavior after upgrading to Atomikos 6.0.0 ? If so, how can we address them?

Steps to reproduce:

Upgrade Atomikos from 4.0.4 to 6.0.0 Run the application Expected behavior:

No warnings should be generated.

Actual behavior:

The two warnings described above are generated.

We are concerned about these warnings and would appreciate any guidance on how to address them.

Hi,

This probably comes from the changes we made in 5.0, see the release notes for how to achieve backwards compatible behaviour with 3.9 and 4.0 applications:
