Yup, there's a bug there. The key is to set isUseJmx(false) in the test
Christian created and then the exception will show up.
Please open an Jira issue for this.

I have tried the nightly snapshot below and the problem still exists there.
Here is how you can reproduce it.
1. Download fresh copy and install
2. Edit conf/activemq.xml and change broker line to
<broker xmlns="http://activemq.apache.org/schema/core"; brokerName="localhost"
dataDirectory="${activemq.data}" schedulerSupport="true">
3. Go to admin console and create a topic,
http://localhost:8161/admin/topics.jsp
4. Go to admin console and create durable subscriber to topic above
http://localhost:8161/admin/subscribers.jsp
5. Delete the durable subscriber using link on same page and it will fail
Repeat all steps above but this time set schedulerSupport=false. Then it will
delete the durable without any errors.
I looked at your unit test and it looks fine, all I can think of is running
activemq from the usual way is behaving differently to the unit test somehow.

Actually, I cannot reproduce this on trunk:
https://github.com/christian-posta/activemq/blob/AMQ-durable-sub-test/activemq-unit-tests/src/test/java/org/apache/activemq/bugs/AMQdurableSubTest.java#L50
Can you try with a nightly snapshot?

Hi,

If I turn off the scheduler in activemq.xml, then this problem goes away so
it's related to the scheduler. This is a very nasty bug because without the
ability to delete durable subscribers, dormant durables will eventually bring
down the server. The offlineDurableSubcriberTimeout doesn't seem to kill the
durable subscriber either. Below is a config I use on the broker.
<broker xmlns="http://activemq.apache.org/schema/core"; brokerName="localhost" dataDirectory="${activemq.data}"
offlineDurableSubscriberTimeout="172800000" offlineDurableSubscriberTaskSchedule="3600000" schedulerSupport="true"
useJmx="true">
