debian update breaks java networking

My testing Debian was recently upgraded to latest version and suddenly java applets stopped working with ConnectionExceptions and ClassNotFoundExceptions. After 1,5 days of searching I found that there is a new config file in /etc/sysctl.d/bindv6only.conf which breaks java networking!!!!

To "fix" it change net.ipv6.bindv6only = 1 to 0 and run:
invoke-rc.d procps restart

java now works again!!! I don't understand why (and I don't care) but this kind of things should be more public and more easy to find... Debian mainteners PLEASE don't break things so silently...

firefox 3.6 and java...

I lost 2 days trying to get new firefox 3.6b4 to use java 1.6 only to find out they changed the way plugins are handeled and that I need a new plugin!

new setting is:

user@server~/firefox36/plugins$ ls -la
lrwxrwxrwx 1 user users 58 2009-12-07 19:47 libnpjp2.so -> /home/user/ibm-java-i386-60.sr6/jre/lib/i386/libnpjp2.so


yours should probably point to something like:

/usr/java/latest/lib/i386/libnpjp2.so
for SUN java or
/opt/ibm-java-i386-60/jre/lib/i386/libnpjp2.so
for IBM java

Lets hope google will index this soon so others don't have to dig too deep...
