Description

Taken from an additional comment on JENA-1618..

It appears to affect the creation of datasets (with inference support) through the http endpoint. In my final test I replaced the config-tdb2 template file with Andy Seaborne`s code, tried to create a new dataset through the web interface and got a similar error (see exception bellow).

Curiously, if I create a dataset with the standard configuration and then change the config file, it seems to work fine.

org.apache.jena.assembler.exceptions.AmbiguousSpecificTypeException: cannot find a most specific type for http://base/#tdb_graph, which has as possibilities: ja:Model tdb2:GraphTDB.
