The key symptoms are highlighted in the output.  The first indicates that schema validation was being performed on the internal tangosol-coherence.xml file that is inside the coherence.jar.  The second message, with the 'This parser does not support specification "null" version "null"' is indicative of the XML parser being unable to process the XML schema definition being used for the validation.  This error could potentially be seen with the internal tangosol-coherence-override-[dev|eval|prod].xml files.

Note: If you have a schema validation error on one of your own configuration files, and you aren't using the Oracle XML Developer Kit, then there is an issue with the contents of your configuration file and you have not encountered this issue.

Changes

This could be encountered after upgrading a system that uses the Oracle XML Developer Kit XML parser, which implements JAXP 1.2, to Coherence 3.7.0.
