Hi,

I try to use GeoPackage to store SimpleFeatures but when I add them,
their IDs become strange. Here there is a running example:
https://github.com/remipassmoilesel/abc-map2/tree/master/src/test/java/org/abcmap/core/shapes

Below a sample of output:

// Before adding (with SimpleFeatureBuilder.buildFeature(null);
fid-6c609a7e_1585d46582c_-7ff9
fid-6c609a7e_1585d46582c_-7ffa
fid-6c609a7e_1585d46582c_-7ffb
fid-6c609a7e_1585d46582c_-7ffc
fid-6c609a7e_1585d46582c_-7ffd
fid-6c609a7e_1585d46582c_-7ffe
fid-6c609a7e_1585d46582c_-7fff
fid-6c609a7e_1585d46582c_-8000

// After adding:
feature1.null
feature1.null
feature1.null
feature1.null
feature1.null
feature1.null

I learned in Javadoc that feature ID format is dependent on storage,
but is this a correct behavior ? Feature identifiers are not supposed
to be unique ?

I was about to use IDs to adapt style, so if IDs are not unique what
is the best strategy ?

Thanks for your help.
