uniqueness violation is detected for unrelated key values

Name: erR10175 Date: 11/19/2003


 
The test
  api/xml_schema/structures/IdConstrDefs/fields/fields00202m/fields00202m3.html#Positive

fails because RI detects identity constraint violation in the document (see below).
The error message contains the following:
fields00202m3_p.xml(16,46): Duplicate unique value [ID Value: 3.0] declared for
identity constraint of element "root".

In the test the fields have different types xsd:string and xsd:decimal.
While the lexical representations are the same, the fields are not equal due to
unrelated value spaces of their types. So the uniqueness constraint is not violated
and the test expects the validator to pass. For more details see the XML Schema
specification.

The bug is found in jdk1.5.0/beta/b28 and is reproducible with all versions
of JAXP 1.2. The bug was not found because the test in JAXP TCK 1.2 and
in JCK 1.5 b08 had a bug (see bug 4953550). Recently the test has been
fixed and renamed from
  api/xml_schema/structures/IdConstrDefs/fields/fields00202m/fields00202m3.html#Negative
to
  api/xml_schema/structures/IdConstrDefs/fields/fields00202m/fields00202m3.html#Positive
