Can't delete message on jms queue

Hi,

I'm trying to delete a message, but for some reason it's not working. I couldn't find an error (not even on server.log), just this message

I tried selecting the message and deleting, and tried using the delete all option as well.

I tried with WLST too, but the path to the queue doesn't seem to exist.

Any ideas of how can i delete that message?

Thanks in advance!
