Michael Glavassevich resolved XERCESJ-1175.
-------------------------------------------
Resolution: Invalid
This is a bug in Java 5.0. It's trying to read META-INF/services files (the
expected format for these is described here [1]) as if they were properties
files. There was a similar issue with XPathFactory (see here [2]). The Apache
version of the JAXP APIs doesn't have this problem and if you include it (the
xml-apis.jar which accompanies Xerces) in the JDK's jre\lib\endorsed [3]
directory the factory lookup mechanism will work correctly.

> Key: XERCESJ-1175
> URL: http://issues.apache.org/jira/browse/XERCESJ-1175
> Project: Xerces2-J
> Issue Type: Bug
> Components: JAXP (javax.xml.validation)
> Affects Versions: 2.8.0
> Environment: Java 5.0
> Xerces 2.8.0
> Eclipse 3.2
> Reporter: Søren Gjesse
> Priority: Minor
>
> When version 2.8.0 of xercesImpl.jar is added to the Java 5.0 classpath the
> Xerces implementation of SchemaFactory is not used by default.
> The reason for this is that the content of the file
> META-INF/services/javax.xml.validation.SchemaFactory in xercesImpl.jar is
> org.apache.xerces.jaxp.validation.XMLSchemaFactory
> It should be
>
> http\://www.w3.org/2001/XMLSchema=org.apache.xerces.jaxp.validation.XMLSchemaFactory
> (note the escape character of the : after http) as Java 5.0 expects a
> SchemaFactory for each schema language in this case
> http\://www.w3.org/2001/XMLSchema
> When running the following with Java 5.0 and version 2.8.0 of xercesImpl.jar
> on the classpath
> import javax.xml.XMLConstants;
> ...
> SchemaFactory factory =
> SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
> System.out.println(factory.getClass().getName());
> the output is
> com.sun.org.apache.xerces.internal.jaxp.validation.xs.SchemaFactoryImpl
> Which is the Java 5.0 (Xerces 2.6.2 derivate) build-in SchemaFactory and not
> the Xerces 2.8.0 SchemaFactory.
> There are several workarrounds one is to run java with the option
>
> -Djavax.xml.validation.SchemaFactory:http://www.w3.org/2001/XMLSchema=org.apache.xerces.jaxp.validation.XMLSchemaFactory
> Others are to use $java.home/lib/jaxp.properties or set the system property
> using System.setProperty(...). See
> http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/validation/SchemaFactory.html#newInstance(java.lang.String)
> for a description of how the SchemaFactory implementation is found.
