Resolution:
=========
Verify if these lines are not modofied or overwritten in the .tra file :
#
# Sets the SAX and DOM JAXP factories to use
#
java.property.javax.xml.parsers.SAXParserFactory org.apache.xerces.jaxp.SAXParserFactoryImpl
java.property.javax.xml.parsers.DocumentBuilderFactory org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

Upgarde environment to JDK 1.7 .

Another workaround is to put in the cdd file the property
    com.tibco.xml.parsers.disabled="true"

Note that the above property does not enforce certain security checks on data parsing and makes data susceptible to outside attacks .
