----- Original Message -----
> Kerberos 1.11 introduced a new configuration variable to override the
> default location of the credential cache at build time. Fedora 18 and up
> have used this new configuration variable to define an alternate default
> cache location (/run/user/$UID/krb5cc/tkt). This bug was initially
> reported against Fedora .
> On Linux and Solaris systems, FileCredentialsCache.getDefaultCacheName()
> defaults to the previously hard-coded location (/tmp/krb5cc_$UID). This
> location will be incorrect if Kerberos was built with an alternative
> credential cache location set. Since this credential cache location can
> be arbitrary, we need to query the Kerberos API for the correct
> location. This patch implements this query using a new JNI call, which
> adds a dependency on libkrb5 for Linux and Solaris systems.
> This patch was prepared against icedtea7-forest/jdk, changeset afaedb56b499.

I had to make some further changes. I didn't realise that it was introducing
a new library dependency and, indeed, hardcoding -lkrb5. I'd assumed that was
