THIS FIX IS ONLY INTENDED FOR WAS 3.0.2 PTF2.

PMR:  26013
APAR:  pq44924
VERSION:  WebSphere Advanced 3.0.2 ptf2
Description:  NullPointerException occurs on connection.close() after the connection has been preempted.  
Solution:  ConnectionPreemptedException is caught and rethrown out of the close method.  The user is responsible for catching the ConnectionPreemptedException and acting accordingly.

Symptoms:  NullPointerException occurs on close of a connection.  After this, executing a query on a statement of some sort will also get a NullPointerException.  Eventually, getConnection will error out as well.

Directions to apply fix:
1) create a directory to store the jar file (e.g. c:\WebSphere\AppServer\efix)
2) copy the jar file into the directory
3) add the directory/jar file to the begining of the admin server's classpath in admin.config:
	com.ibm.ejs.sm.adminserver.classpath=C:/WebSphere/AppServer/efix/PQ44924.jar; ...
4) Stop and restart the Admin Server  

In addition, it is essential that the exception 'ConnectionPreemptedException' , which extends SQLException, is always caught in
your code.  For example, if closing the connection in the finally clause, make sure to add something like the following code:

finally{
   if (conn != null) {
      try {
         conn.close(); }
      catch (ConnectionPreemptedException ex) {
         //can ignore an exception here since we are trying to close the connection
       }
   }
}
