Fixed Issues

Issue Resolution ID

The Publish operation now supports the ADMIN.QUEUE destination, which allows you to refresh the connection or reconnect listeners at runtime. This is useful for maintenance or error recovery without stopping the Mule application. For more information, see Configure ADMIN.QUEUE to Refresh Connections.

Issue Resolution ID

In IBM MQ 1.7.4, memory leak issues were resolved for Mule runtime versions running on Java 8. However, Mule runtime versions running on Java 11 or 17 used reflection, which caused IllegalAccessException errors. These are resolved now, and the connector no longer experiences memory leaks or reflection-related errors on Java 11 or 17.
