Fixes are available

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

Local fix

Set "Access to internal server classes" to allow through the
adminConsole.

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V6.1.0 using Java 2 Security or      *
*                  ibm.websphere.internalClassAccessMode       *
****************************************************************
* PROBLEM DESCRIPTION: Enabling Java 2 Security or using the   *
*                      ibm.websphere.internalClassAccessMode=r *
*                      estrict can cause a                     *
*                      ClassNotFoundException.                 *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
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 PK89310 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.29 of WebSphere Application Server V6.1.
