JDBC Datastore - Unable to map java.net.URI

When loading a feature collection from WFS (WFS-NG) with the following attribute type description (GetFeatureType):

the type is mapped to "java.net.URI". When trying to store this in a JDBC-datastore the following error occures:

Unable to map java.net.URI

The problem is that no mapping for java.net.URI to a SQL type exists:

A possible solution could be to map this field to a string based type (e.g. VARCHAR).
