Your Java thin application client no longer needs additional code to set security providers if you have enabled security for your WebSphere® Application Server instance. This code found in iSeries® Java thin or pluggable application clients should be removed to prevent migration and compatibility problems. The java.security file from your WebSphere instance in the properties directory is now used to configure the security providers.
