AbstractPropertySet are not stored and retrieved properly from UI when using JdbcFeatureStore

[cboulme]

I created a new property which extends AbstractPropertySet.
From UI I create a new property and entering the value a,b,c, this is stored in database as [a,b,c].
Then when displayed on UI, it is displayed as [b, [a, c]].

Same if I just set the value as a, it is stored in db as [a] and then displayed as [[a]].
I can't find the line of code making this happens, and I didn't get the issue when using in memory store

FYI if I override the asString in my class which extends AbstractPropertySet with:
@OverRide
public String asString() {
if (value == null) {
return null;
}
return value.stream().collect(Collectors.joining(getListDelimiter()));
}
It saves it in database as a,b,c and display it correctly on UI.
I will do more tests to see if it is enough
