tpasswd exists with NPE when password file is missing

[GoogleCodeExporter]

What steps will reproduce the problem?

1. run tpasswd -c xxx yyy

What is the expected output?

tpasswd should warn that no password file was defined, and exit with an error

What do you see instead?

$ ./cluster-home/bin/tpasswd  -c xxxx dd
Using parameters:
-----------------
password_file.location   = null
encrypted.password   = false
-----------------
Exception in thread "main" java.lang.NullPointerException
    at java.io.File.<init>(File.java:251)
    at com.continuent.tungsten.common.security.PasswordManager.try_createAuthenticationInfoFiles(PasswordManager.java:295)
    at com.continuent.tungsten.common.security.PasswordManagerCtrl.main(PasswordManagerCtrl.java:229)

What is the possible cause?

N/A

What is the proposed solution?

the password file parameter should be mandatory, and as such checked for 
completion before any action is taken.
