I'm trying to raise a bug with Sun about the sun.security.krb5
implementation. Unfortunately this is somewhat hampered by my suffering
from RSI at the moment.
The problem is a straightforward resource leak, as you can see if you
look at this:
in particular, at
You'll see that sun.security.krb5.internal.UDPClient has no close()
method; and the UDPClient-using code path in sun.security.krb5.KrbKdcReq
(which has a few other close-to-the-coalface errors) consequently leaks
FDs (unlike the TCP path, which has a try/finally that closes the socket
We're seeing a krb5 client application (the Yale CAS SSO) keel over in
no time due to FD exhaustion. A trivial fix (the non-whitespace part of
the diff is 8 lines) sorts this out.
Prepping a test case is somewhat difficult when this email represents
most of the typing I'm going to get done today :-(
