Weblogic SAAJ version problem : java.lang.UnsupportedOperationException: This class does not support SAAJ 1.1

Recently I came across a weird issue where I get
java.lang.UnsupportedOperationException: This class does not support SAAJ 1.1
Whenever I tried to run my application in my integrated weblogic 10.3. After some research on net I found out the fix for this here
The Reason for the problem is Weblogic’s default SAAJ implementation, in package weblogic.webservice.core.soap, is flawed. Hence we need to override the properties to use a better implementation weblogic.xml.saaj package.
To resolve this issue, set the below property either in your JDeveloper’s run settings for Server or in startWeblogic script.
