Anyone know what this means? - "/ by zero" is not the world's most helpful
error message:

javax.net.ssl.KeyManagerFactory.init was called like this:

           kmf.init( ks, "".toCharArray() );

where ks is a "PKCS12" KeyStore loaded from a .p12 file (which is correctly
interpreted by other (non-Java) tools, so I'm not looking at an invalid .p12
file as the first thing to suspect).
