Error description

A ClassNotFoundException can be experienced when setting

.
The exception - ClassNotFoundException or NoClassDefFoundError -

  one of the service methods of the servlet:
  perfservlet60. Exception thrown :
java.lang.NoClassDefFoundError:
  com.ibm.ws pmi stat.StatisticImpl
   at java.lang.J9VMInternals.verifyImpl(Native Method)
.
The following classes had to be exempted in
com.ibm.ws.runtime_6.1.0.jar/plugin.xml to make
PerfServletApp.ear work
in mode RESTRICT:
.
      <exception name="com.ibm.ws.pmi.stat.StatisticImpl" />
      <exception name="com.ibm.ws.pmi.stat.CountStatisticImpl"
/>
      <exception name="com.ibm.ws.pmi.stat.DoubleStatisticImpl"
/>
      <exception name="com.ibm.ws.pmi.stat.RangeStatisticImpl"
/>
      <exception
name="com.ibm.ws.pmi.stat.BoundedRangeStatisticImpl" />
      <exception name="com.ibm.ws.pmi.stat.AverageStatisticImpl"
/>
      <exception name="com.ibm.ws.pmi.stat.TimeStatisticImpl" />
.
For J2C, the classes are as follow:
.
com.ibm.ejs.j2c.ThreadIdentitySecurityHelper
com.ibm.ws390.jta.TransactionManager
com.ibm.ejs.j2c.PrivExAction
com.ibm.ejs.j2c.J2CUtilityClass

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V6.1.0                               *
****************************************************************
* PROBLEM DESCRIPTION: A NoClassDefFoundError or               *
*                      ClassNotFoundException is thrown for    *
*                      a set of com.ibm.ws.pmi.stat classes.   *
****************************************************************
* 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.ws.pmi.stat.AverageStatisticImpl,
com.ibm.ws.pmi.stat.BoundedRangeStatisticImpl,
com.ibm.ws.pmi.stat.CountStatisticImpl,
com.ibm.ws.pmi.stat.DoubleStatisticImpl,
com.ibm.ws.pmi.stat.RangeStatisticImpl,
com.ibm.ws.pmi.stat.StatisticImpl, and
com.ibm.ws.pmi.stat.TimeStatisticImpl. 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 or
NoClassDefFoundError for these classes.

APAR PK95962 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.31 of WebSphere Application Server
V6.1.
