Error description
The following exception is seen in the servant after the customer upgraded from 6.1.0.19 to 6.1.0.24. This is only seen when the following option is set to "restrict" through the adminconsole: Application servers > servername > click on the drop down menu > Access to internal server classes When this is set to "allow" the exception does not occur (the default value for this property is allow). An example of the exception seen in the servant joboutput is, BBOO0220E: J2CA0009E: An exception occurred while trying to instantiate the ManagedConnectionFactory class com.ibm.ws.rsadap ter.spi.WSManagedConnectionFactoryImpl used by resource jdbc/Sessions : java.lang.ClassNotFoundException: com.ibm.ejs.j2c.ThreadIdentitySecurityHelper .at com.ibm.ws.classloader.CompoundClassLoader.findClass .at com.ibm.ws.classloader.CompoundClassLoader.loadClass .at java.lang.ClassLoader.loadClass .at com.ibm.ejs.j2c.J2CUtilityClass.createSecurityHelper . . at com.ibm.ws.webcontainer.httpsession.BackedHashtable. getDataSource . . .at com.ibm.ws.wswebcontainer.WebContainer.run
