This is a very very old version of IcedTea, released on 2012-10-17 and long
since unsupported. The latest version is 2.6.7: http://bitly.com/it20607

Well, the rt.jar is provided by your bootstrap JDK so what it contains depends
on how you configure the build, which you haven't specified.

Classpath does have this method now, so this is another reason its overdue for
a new release...

While I agree we can safely remove the -u, the real issue here is that your
environment is not correctly configured, which may cause problems elsewhere in
the build. Did it work with TZ set?
