OIM 11g R1: Usr Process Triggers Not Working on Concurrent Calls

Question

Version: 11.1.1.5.7
I am making two API calls to change a user's password.
The first call uses the ADMIN to generates a random password for a user.
The second call uses the user to change his/her own password.
I am getting an issue where one of the calls does not kickoff the Usr Process Trigger.
This happens like 1 in 15 tries.
Is this a bug or am i missing sometime?
Given below is the test code.
import java.util.Hashtable;
import java.util.Random;
import java.util.logging.Logger;
import oracle.core.ojdl.logging.ODLLogger;

        env.put(OIMClient.JAVA_NAMING_FACTORY_INITIAL, ctxFactory);
        OIMClient oimClient = new OIMClient(env);
        OIMClient userOimClient = new OIMClient(env);
        //Admin changes User Password
        oimClient.login("xelsysadm", "Password1".toCharArray());
        UserManager usrMgrOps = oimClient.getService(UserManager.class);
        String generatedPassword = "a" + generateRandomUserPassword(30);
        System.out.println("Generated Password: " + generatedPassword);
        usrMgrOps.changePassword("tstark", generatedPassword.toCharArray(), true);
        //User changes their own Password
        userOimClient.login("tstark", generatedPassword.toCharArray());
        String myPassword = "Password20";
        AuthenticatedSelfService authOps = userOimClient.getService(AuthenticatedSelfService.class);
        authOps.changePassword(generatedPassword.toCharArray(), myPassword.toCharArray() , myPassword.toCharArray());
        System.out.println("My Password: " + myPassword);
        oimClient.logout();
        userOimClient.logout();
    public static String generateRandomUserPassword(int length){
        if(length < 1)
            throw new IllegalArgumentException("length < 1: " + length);
        char[] characters = new char[62];
        char[] randomUserPassword = new char[length];
        Random random = new Random();
        for (int i = 0; i < 10; ++i)
              characters[i] = (char) ('0' + i);
        for (int i = 10; i < 36; ++i)
          characters[i] = (char) ('a' + i - 10);
        for (int i = 36; i < 62; ++i)
          characters[i] = (char) ('A' + i - 36);
        for (int i = 0; i < randomUserPassword.length; ++i)
            randomUserPassword[i] = characters[random.nextInt(characters.length)];
        return new String(randomUserPassword);

Set the "Off-line" flag to true in your "Change User Password" process task.
