java (Sun and OpenJDK) environments contain bogus XFILESEARCHPATH

[Nonconventionally Creative]

Java applications will receive the bogus environment setting
XFILESEARCHPATH=/usr/dt/app-defaults/%L/Dt
NLSPATH=/usr/dt/lib/nls/msg/%L/%N.cat

These override the sane default paths that are otherwise used

Ubuntu Jaunty
openjdk-6-jre 6b14-1.4.1-0ubuntu13
sun-java6-jre 6.20dlj-0ubuntu1.9.04

Ubuntu Lucid
openjdk-6-jre 6b17~pre3-1ubuntu2
openjdk-6-jre 6b18-1.8-0ubuntu1

apt-file search shows no existence of /usr/dt; the app-defaults directory should be something like /etc/X11/app-defaults/%N, with no %L (locale) parameter.
Simply appending ":%D" to the current value of XFILESEARCHPATH would invoke the intended behaviour, just in case that directory ever existed and was needed.

The quickest way to detect the effects of a mis-set XFILESEARCHPATH:
Runtime.getRuntime().exec("xterm");
Note that the ctrl-click menu includes the heading "(no app-defaults)" and the "backarrow" option is checked, causing the backspace to generate the wrong code (might not be noticed immediately since the readline library used by bash is forgiving, but a program that relies on the terminal driver (e.g. cat) or a terminfo-based program will malfunction)

I don't know enough about NLSPATH to determine whether it breaks anything, but I expect it does.

Since it occurred across implementations, I thought at first it might be a configuration problem.
But, the offending strings, and thus the bug, are in jre/lib/amd64/libjava.so, which is also in sun-java5 and the jdk7 snapshot I downloaded a while ago.
(How do I add a package to the bug?)

marking the sun-java6 task as wontfix, same as the upstream status

Accepted openjdk-6 into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
