Hello,
I'm using JENA API 2.11.2 . When I load some data from DBpedia and call
the getFloat() method on a Literal object I get the following exception:
com.hp.hpl.jena.datatypes.DatatypeFormatException: Lexical form 'NAN' is
not a legal instance of Datatype[http://www.w3.org/2001/XMLSchema#float
-> class java.lang.Float] Lexical form 'NAN' is not a legal instance of
Datatype[http://www.w3.org/2001/XMLSchema#float -> class
java.lang.Float] during parse
-org.apache.xerces.impl.dv.InvalidDatatypeValueException:
cvc-datatype-valid.1.2.1: 'NAN' is not a valid value for 'float'.

com.hp.hpl.jena.graph.Node_Literal.getLiteralValue(Node_Literal.java:39)

com.hp.hpl.jena.rdf.model.impl.LiteralImpl.getValue(LiteralImpl.java:98)
at
com.hp.hpl.jena.rdf.model.impl.LiteralImpl.getFloat(LiteralImpl.java:216)
This looks like a bug to me because NaN is allowed in XMLSchema specs
for float values and additionally, Java contains a Float.NaN constant.
Kind regards,
Lorenz
