knox failed to start because knoxcli failed with "java.lang.NoSuchFieldError: DEFAULT_XML_TYPE_ATTRIBUTE"

On some machines knox 1.3.0 works fine. But on other machines, knox gateway failed to start. We narrowed down the problem to be simply this:

/opt/knox/bin/knoxcli.sh create-master --master knoxmaster

Further investigation found out that there are mixed version of 2.7.4 and 2.7.2 eclipse persistence jars in knox/dep folder:

eclipselink-2.7.4.jar

org.eclipse.persistence.core-2.7.2.jar

sdo-eclipselink-plugin-2.3.1.jar

jaxws-eclipselink-plugin-2.3.1.jar

org.eclipse.persistence.moxy-2.7.2.jar

org.eclipse.persistence.asm-2.7.2.jar

org.eclipse.persistence.sdo-2.7.2.jar

The root cause is that we should upgrade jaxws-ri from 2.3.1 to 2.3.2 so that eclipse persistence class will have the same 2.7.4 version.
