Cannot successfully edit an imported bilingual record

I created the following small test file.

I can successfully import the file using "Contribute" -> Import new records".

When I view the record, the title, description and organisation are shown in Dutch when I choose Dutch in the GUI, and in English when I choose English in the GUI.

I noticed though, that "en" is listed as a Metadata language, independent of whether I choose Dutch or English.

When I push the "Edit" button, the title, description and organisation can be seen in both languages in the "Dataset" tab.

When I then go to the "Record" tab, it is shown correctly that the languages of the catalog record are English and Dutch.

However, when I then try to go back to the "Dataset" tab, nothing happens.

The log file shows a NullPointerException, see log.txt.

It has something to do with dct:language:

I tested the plugin with the code at commit 81e6433.

This is probably due to a missing commit in core (geonetwork/core-geonetwork#9116). Could you attempt to apply it to see whether it alleviates your issues?

We should improve the version handling for this plugin, as currently main is dependent on a core change (which, if not accepted, should become a patch in this plugin).

Great, thanks, yes, that solves the issue.
