ca-certificates-java deletes libnss3.so and nss.cfg, crashing Java when launched

[Sam Bethmann]

Apparently this bug has reappeared, except this time the update to ca-certificates-java also deletes (or blanks, I can't remember if nss.cfg was there or not when I checked it) the file nss.cfg:

https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/855171

I am using Ubuntu 12.04.2 LTS, version 20110912ubuntu6 of ca-certificates-java, and version 7u25-2.3.10-1ubuntu0.12.04.2 of openjdk-7-jre.

I was installing p7zip when apt-get alerted me of a security update to Java 7 (openjdk-7-jre). When I updated and started my Bukkit (Minecraft) server (a jarfile), the application crashed (see part 1 of attached crash.txt). The crash was due to a java.io.FileNotFoundException in /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/nss.cfg. The jarfile was working perfectly fine before I updated openjdk-7-jre (and possibly some dependencies.) I tried to fix this by creating the nss.cfg and filling it with this:

#Content of nss.cfg
name=NSS
nssLibraryDirectory=${java.home}/lib/amd64
nssDbMode=noDb
attributes=compatibility

After which I started the jarfile again, and another java.io.FileNotFoundException appeared... this time /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/libnss3.so was missing (see part 2 of attached crash.txt). I have not been able to find a solution to fix this, nor do I have another libnss3.so on my machine (to my knowledge.)

Unlike the fix reported in the bug report above, 'sudo apt-get install --reinstall libnss3 libnss3:i386' does not fix this problem.

Status changed to 'Confirmed' because the bug affects multiple users.
