Here are two potential issues that might be affecting you:

1. Java 7 appears to switch the default encryption type order. Details:

   • Java 7 Kerberos Issue - AES128 Corrupt checksum
     
     

2. You did't say what specific version of JDK 7 you are using, but there was a bug in earlier versions of JDK 7 that prevented loading keytab files via "file:" URLs:

Another user on SO worked around the last issue by modifying Spring source:

• BadCredentialsException: Kerberos validation not succesfull
