That can depend on the reason why you want to kinit.

If you're looking to have Kerberos credentials available for the java
process so that it can authenticate it self to other services, then
you may find it better to run the java process from k5start.  As I'm
lazy I won't try to explain how it all works here, but will rather
just quote the first paragraph of the manpage:

#---8<-----------------------------------------------------------------
k5start obtains and caches an initial Kerberos ticket-granting ticket
for a principal.  k5start can be used as an alternative to kinit, but
it is primarily intended to be used by programs that want to use a
keytab to obtain Kerberos credentials, such as a web server that needs
to authenticate to another service such as an LDAP server.
#---8<-----------------------------------------------------------------

If that sounds like the sort of solution you're after, I can highly
recommend k5start (and krenew from the same package).

Cheers.

Dameon.
