The classloader code has been modified. The updates to com.ibm.ws.classloader.CompoundClassLoader.java are as follows: 1. Update the static initializer to issue an audit message when errors are encountered during setup of the plugin class. 2. Update method _defineClass where it catches exception Throwable so that an audit message is issued. The updates to com.ibm.ws.classloader.EJBJarClassLoader.java are as follows: 1. Update preLoadInterfaces where it catches an Exception. A trace audit message will be issued with text that indicates which Server, Application, Exception and potentially the classname being loaded. This will require factoring of the code to place the classname in a local method variable. Also, the loadClass calls should probably be moved outside the parameter list on the calls to _resolveClass. 2. _resolveClass should be updated to have try catch logic to allow a message to be issued for missing classes found during this process. The updates to com.ibm.ws.classloader.ClassGraph are as follows: 1. Update the various places in the class where catches for exceptions are done and no action is taken. The action to be taken in these cases will be to issue a warning message (tr.audit) that explains the failure and to print the stack trace. An example of one of the places is in getManifestPaths method. A new JarFile and new Manifest class are provided and the IOException is caught and no action is taken. If we issue a message with appropriate information about the exception it will surface potentially misspelled items in the Manifest Class-Path. The udpates to com.ibm.ws.classloader.SinglePathClassProvider.java are as follows: 1. Update catch blocks in the code to issue warning messages (use tr.audit) for missing jar files. Some of the failures encountered are normal operation. Not all catch blocks need to have a message issued. Additional Internal Defects corrected: 83145 83155 83205 83233 83237 83247 83255 83269 83368 83400 83619 83860 83934 83967 83999 84006 APAR PQ65215 is associated with SERVICE LEVEL W401400 of WebSphere Application Server V4.0.1 for z/OS and OS/390.
