It turns out this is a bug in Oracle's JRE/JDK. See Issue 50 (#50) for more detail.

This should have been fixed in JRE/JDK 8 Update 66. Could you try it please?

from mqtt-spy.

It's JRE/JDK 8 Update 65/66.

It does still not work correctly. Actually I have the following strange
behaviour using Java(TM) SE Runtime Environment (build 1.8.0_65-b17):

1. Type '#' in subscription topic field, click "Subscribe" -> Message box
   "Cannot subscribe to an empty topic"
2. Press Enter (with focus in subscription topic field) -> Subscription of '#'
   is done and works
3. Unsubscribe and close tab
4. Type 'foo' in subscription topic field, click "Subscribe" -> Subscription of
   '#' is done (and works), 'foo' is not used

The click on "Subscribe" uses always the last topic that was entered using Enter
and not the one, that is present in the input field.

Sorry - you are right - there problem is till there - my fault! Just checked the Oracle website and it looks like this fix is going to make it to JRE/JDK 8 Update 72.

I've just spotted this one now... yes, same thing happening to me - I'm so glad someone reported it - I'm back in the UK setting up a computer, loaded the latest MQTT-SPY and could not subscribe to anything... at least now I know why.. do we know when this update is coming out?

from mqtt-spy.

JRE/JDK 8 Update 72 is scheduled for January. In the meantime, you can either press the Enter key after typing the subscription topic or go back to Update 51.

0.3.1 beta build 24 contains a workaround for the JRE bug - please let me know if that resolves the problem.

from mqtt-spy.

YUP that does it – thanks for your continued efforts – still the best out there.
