java.lang.NullPointerException and other problems

[swdick]

I recently had to do a clean install of W10 and after udating Minimserver and Minimwatch I got problems:
* java.lang.NullPointerException error
* a lot of errors lik this:
Warning: truncating incorrect value for DATE tag 1985/1997 in file Componisten/Brahms, Johannes (1833-1897)/Clarinet Trio & Piano Trio No. 2/08 Johannes Brahms - Trio for clarinet (or viola), cello & piano in A minor, Op. 114; Allegro.flac

Minimserver started for a second (showed its icon green) but then stopped and gave the above errors.

Please post the complete stack trace for the NullPointerException. This should be preserved in a minimserver-crash file in this folder:

C:\Users\your-user-name\AppData\Roaming\MinimServer\data

The AppData folder is hidden by default in Windows Explorer. You can view it by typing the full path into the Explorer address bar.

The value 1985/1997 isn't valid for the Date tag. The value must be YYYY or YYYY-MM or YYYY-MM-DD.

Thanks for your quick reply.
There is no Minimserver map or file in this place, only Minimwatch files:
.config, config.lock, .config.save and .log

[simoncn]

The MinimServer/data folder (if present) contains MinimServer files. The MinimWatch/data folder (if present) contains MinimWatch files.

From your post, I thought you were running MinimServer on Windows 10. Is this correct or are you running it on some other device?

[swdick]

No, I'm sorry to be unclear. Minimserver runs on my Synology Nas.
On the NAS I see several files such as Minimserver-out.log and a (lot of) -crash files. I attach them.

Thanks for this. This problem could occur if you had previously browsed to an alpha-grouped container and then disabled alpha grouping. The control point is not aware that alpha grouping has been disabled and has attempted to browse to a container that no longer exists. This should produce a warning message but not a NullPointerException. Does this seem consistent with what you were doing before the problem occurred?

[swdick]

I suppose it has to do with the settings of the properties in Minimwatch.
I have reinstalled W10 and lost all the settings of the properties of Minimwatch. I did use grouping and all sorts of properties which I forget now.
In the properties of Minimwatch nearly all fields are greyed out and can not be changed.

[simoncn]

These properties are greyed out because you are running MinimServer 2 Starter Edition on your Synology NAS. To get back all the settings you had previously, you can activate a free 30-day trial license. To keep these settings after 30 days, you need to purchase a MinimServer 2 full license.

You can find more information about this on this page.

I activated a trial licence and all seems well now.
Thanks.

What was the cause of the problem? I understand that the free version should also work. Is the AlphaGrouping the problem?

[simoncn]

The NullPointerException with the free version and alphaGroup is a bug that will be fixed in the next MinimServer update. Thanks very much for letting me know about this.
