Description

I have a toy example turtle file to be read by JENA:

@prefix jpn:   <http://kaiko.getalp.org/dbnary/jpn/> .
@prefix dbnary: <http://kaiko.getalp.org/dbnary#> .
@prefix lemon: <http://www.lemon-model.net/lemon#> .

jpn:__ws_1_青は藍より出でて藍より青し__Idiom__1
        a                   lemon:LexicalSense ;
        dbnary:senseNumber  "1"^^<http://www.w3.org/2001/XMLSchema#int> ;
        dbnary:synonym      jpn:出藍の誉れ , jpn:cf. , jpn:後生おそるべし ;
        lemon:definition    [ lemon:value  "弟子が研鑽し師を凌駕すること又はその可能性があるということ。さらには、それは、恥ずべきことでなく望ましいということ。"@ja ] .

I create a default Model m and read the file using m.read(url, "TURTLE").

JENA breaks with the following stack trace:

The faulty IRI is jpn:cf. (an IRI with a trailing dot). If I replace it by jpn:cf.x (note that the IRI is not dot terminated anymore, then the turtle file is read whit no error.

As far as I know, jpn:cf. is a valid IRI and there is no reason to consider this trailing dot as a turtle termination char (as the error message suggests) as it is part of the IRI.
