Random Kerberos validation error with Spring

Question

I sometimes get in my application, say 1-10 times within 24h, the following error:

org.springframework.security.authentication.BadCredentialsException: Kerberos validation not succesfull
...
Caused by: java.security.PrivilegedActionException: GSSException: Defective token detected (Mechanism level: GSSHeader did not find the right tag)
    at java.security.AccessController.doPrivileged(Native Method)
    at javax.security.auth.Subject.doAs(Subject.java:416)
    at org.springframework.security.extensions.kerberos.SunJaasKerberosTicketValidator.validateTicket(SunJaasKerberosTicketValidator.java:67)

Any ideas to how this error comes to be? As I said, it appears very random and does not happen very often.
