Features

  • Redelivery policy options (maximum redeliveries and outcome) were added to the connector’s configuration.

Known Issues

  • Under some scenarios, users can get an InterruptedException error on the Mule app startup. This does not affect the proper operation. To get rid of this message, check the Skip Connectivity Test checkbox in the connector’s configuration.

February 22, 2019

Compatibility

Software Version

October 23, 2018

Compatibility

Known Issues

  • Automatic completion of queue and topic names, subscriptions and rules may not work in Design Center.

  • In Design Center, the Live View feature will not work for most operations. In addition to this, the application log may be flooded with several Could not serialize object errors.

  • The connector leaks connections while publishing a message to a topic using the default caching strategy. As a workaround, configure the connector to disable the caching strategy.
