APAR status

• Closed as program error.

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

  adminConsole.

  ****************************************************************
  When Java 2 Security is turned on or the
  ibm.websphere.internalClassAccessMode custom property is
  enabled, a ClassNotFoundException may be raised for the
  following classes:
  com.ibm.ejs.j2c.ThreadIdentitySecurityHelper,
  com.ibm.ejs.j2c.PrivExAction, or
  com.ibm.ejs.j2c.J2CUtilityClass. These classes were
  incorrectly part of a set of classes being protected from
  application access.
  

Problem conclusion

• The list of protected WebSphere Application Server classes was
  updated to avoid a ClassNotFoundException for these classes.
  
  APAR PM02282 is currently targeted for inclusion in Service
  Level (Fix Pack) 6.0.2.39 of WebSphere Application Server
  V6.0.1.
