activemq artemis - Can't set confirmationHandler on a connection with confirmation-window-size < 0 error when deployBridge with DEFAULT_CONFIRMATION_WINDOW_SIZE(-1)

Question

I try to deploy Core Bridge via ActiveMQServer.deployBridge(BridgeConfiguration config), I create BridgeConfiguration with default value (DEFAULT_CONFIRMATION_WINDOW_SIZE = -1) for confirmationWindowSize

and put it in ActiveMQServer.deployBridge(BridgeConfiguration config), but after that, I get the errors

You can't set confirmationHandler on a connection with confirmation-window-size < 0. Look at the documentation for more information.

What am I doing wrong or is it a bug?

Artemis version 2.16.0

Answer 1

This looks like a minor bug with the default value for org.apache.activemq.artemis.core.config.BridgeConfiguration#confirmationWindowSize. Currently it is using this:

private int confirmationWindowSize = ActiveMQClient.DEFAULT_CONFIRMATION_WINDOW_SIZE;

However, it should be using this:

private int confirmationWindowSize = ActiveMQDefaultConfiguration.getDefaultBridgeConfirmationWindowSize();

You can work around this issue by setting the confirmation window size manually, e.g.:

BridgeConfiguration myBridgeConfiguration = new BridgeConfiguration();
myBridgeConfiguration.setConfirmationWindowSize(ActiveMQDefaultConfiguration.getDefaultBridgeConfirmationWindowSize());

I opened a Jira issue for this, sent a PR, and the PR has been merged. The fix will appear in ActiveMQ Artemis 2.17.0.
