Description

When deleting a message from a queue using the web console a NullPointerException is thrown on the server side when committing the transaction.

This only happens in case logger.level=INFO or higher is used because the Exception occurs when trying to log the acknowledge for the deleted message.

The reason is that the ServerConsumer used to determine the session is null at this point as it is not provided by the caller.

The attached stack trace shows the exact location.
