[CBUS] Exception after upgrade to OH 3.2.0 release

[guitarglen]

Overview:
The CBUS binding is throwing an exception on startup, following upgrade to OH 3.2.0. I have not been running any milestone builds for this release, so cannot confirm where this was introduced, but can confirm it worked correctly under 3.1.x, just prior to upgrade.
Have tried multiple restarts and clearing the OH cache (via openhab-cli)

As a result, the cbus bridges remain offline, and as would then be expected, all 'downstream' cbus things are in an "ERROR:BRIDGE" state.

This has also been experienced by another user as well (see https://community.openhab.org/t/c-bus-binding/130366), although they were trying to setup cbus binding from scratch under 3.2.0, not realising this was a regression.

Details:
The following is the TRACE level log on startup for the CBUS binding (I have truncated after the first few things loaded for readability - No other errors beyond the listed exception).

Hi there - Thanks for sorting through this so quickly. I have run through a further set of tests as follows:

Startup:

• PASS: Original error as described in this ticket has been resolved. Bridge devices and all dependent devices come online
• PASS: Group levels read from CBUS and reflected in OpenHAB

Level Channel:

• PASS: Level changes made in OpenHAB sent to CBUS devices and reflect changes
• PASS: Changes made to CBUS levels are reflected in OpenHAB

Light Channel:

• PASS: Switch state changes made in OpenHAB sent to CBUS devices and reflect changes
• PASS: Changes made to CBUS switch stated are reflected in OpenHAB

Transient cGate connection

• PASS: When cGate stopped, cGate network moved to 'Error' state. Bridges and dependent devices all moved to "ERROR:BRIDGE" within 1 minute.
• NOTE: Whilst the binding went offline gracefully, an exception was thrown about 1 minute later - See details below. Not aware if this is a regression, or existing behaviour from 3.1.x as well. Does not impact operation however
• PASS: When cGate restarted, cGate network reverts to online, Bridge devices come online, along with all dependent devices. Network scan completed, and current CBUS states reflected in OpenHAB

Logic:

• PASS: Rules triggered by cBUS 'received command'

Shutdown:

• PASS cGate Session cleanly quit/closed
• NOTE - While OpenHAB shutdown completes, noted the exceptions listed further below during shutdown. I cannot be certain this is a regression from 3.1.0 behaviour, and was not consistent across the test runs, with it only occuring 2/3 times. Obviously does not impact any usability of binding.

Hope this helps, and thanks again.

[jpharvey]

@guitarglen Thank you for the testing. I can't reproduce either of the exceptions but will keep trying.
The one for cgate connection loss doesnt make any sense as the code in CBusCGateHandler has a try/catch in the connect method to handle that exception and that is what printed the Failed to connect to CGate Debug message. So something odd is happening for you. But i dont believe either of them are related to the patch.

[guitarglen]

@jpharvey - The testing is the least I can do to help, seeing as I am not (yet !!) in a position to do Java coding. I would agree - The fix you have provided has resolved the original issue as described in this ticket, and the exceptions I observed do NOT affect any operations nor functionality, nor do I have any evidence to suggest they are regressions from the patch (Given their non-impacting nature, they could have been there all along for me, without being seen).

If/when I can create consistent reproduction steps for the other issues, I will raise further bug tickets (but very low priority), for future consideration.

From my perspective, the private JAR built on this fix has now been running solidly for nearly 2 days in my prod system, and CBUS is one of the largest/highest use integrations in my system.

Cheers again.
