Looks like this does not matter at all, as long as it runs CUPS. Anyway:
Linux kernel (2.6.36-tuxonice) on a Gentoo system (Gentoo Base System
release 2.0.1-r1)

> JDKversion

Reproduced with dev-java/icedtea-6.1.9.1 (USE="doc examples hs19
javascript nio2 nsplugin nss pulseaudio xrender -cacao -debug
-elibc_FreeBSD -systemtap -zero").

Looks like it applies to current JDK6 or JDK7 revisions in hg, see my
earlier mail.

Irrelevant, this is a software problem.

If it cannot be reproduced by adding printers or changing their
availability, the method using the remote.cache file for CUPS can be
used to simulate it. (You can also use the printers.conf configuration
file for CUPS, it is usually placed in /etc/cups/.) See my earlier mail.

You may want to have a look at
<URL:http://cups.org/documentation.php/doc-1.4/ref-cupsd-conf.html#FileDevice>,
which describes that "file" URIs are legal in CUPS.


Some further notes on CUPS device URIs:

DeviceURIs can be "ipp" URIs, but also, for example, start with
"usb://". As far as I can tell, OpenJDK does not support "usb" URIs, so
the code I mentioned earlier throws an IOException, and the
ClassCastException does not happen. "file" URIs /are/ supported by
OpenJDK, so the ClassCastException is thrown.


The build descriptions (ebuild files) for the mentioned Gentoo packages
are available from
<URL:http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/>.


Please let us know the bug number after you’ve filed it.

By the way, no need to Cc me, I’m a subscriber of this list.
