2.5. IBM JRE and the Java Security Manager

IBM JRE uses a default policy provider which does not work correctly with the JBoss Enterprise Application Platform security policy. You must change the JRE configuration to use the standard policy provider, if you want to use the IBM JRE to host JBoss Enterprise Application Platform with the Java Security Manager enabled.
To configure the JRE configuration for the IBM JRE, edit the JAVA_HOME/jre/lib/security/java.security file, and set the policy.provider value to sun.security.provider.PolicyFile.
