two identity-constraints with the same {name} and {target namespace} are allowed

Name: erR10175 Date: 12/26/2003


 
The test in JCK 1.5
  api/xml_schema/structures/IdConstrDefs/targetNS/targetNS00101m/targetNS00101m2.html#Negative

fails because RI does not detect two identity-constraints defined with the same {name}
and {target namespace}.

The XML Schema Part 1: Structures (Section 3.11.1 The Identity-constraint Definition Schema
Component) reads:

"Identity-constraint definitions are identified by their {name} and {target namespace};
Identity-constraint definition identities must be unique within an žXML Schemaž."

So, the test schemas (see below) violate that constraint and an XML Schema validator must
report an error.

The bug is found in jdk1.5.0/beta/b32 and is not reproducible with previous builds.
 
The bug seems to be in incorrect source file handling, because if the schema is in
the current working directory and its basename used, the tests reports the error
as expected. If the full path name of the schema file is used, the validator does not
report any error. (see log below)

To reproduce the bug put the following five files in your current working directory,
compile and run the test.java as log shows.

Warning: validation was turned on but an org.xml.sax.ErrorHandler was not
set, which is probably not what is desired. Parser will use a default
ErrorHandler to print the first 10 errors. Please call
the 'setErrorHandler' method to fix this.
