Description

• In testcase "testDelegationTokenOperations", the exception message is checked but in case it does not match the assertion, the exception is not printed. This happens 3 times.
• Assertion messages can be added
• Fields called "httpSpnegoKeytabFile" and "httpSpnegoPrincipal" can be static final.
• There's a typo in comment "avaiable" (happens 2 times)
• There are some Assert.fail() calls, without messages.
