just add these two line on your sources.list under /etc/apt 

deb http://us.archive.ubuntu.com/ubuntu/ karmic-updates multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ karmic-updates multiverse

and do the thing ( sudo apt-get install  sun-java5-jdk ) 

enjoy

I just tried this and still no luck.
1st - added the two lines, then 'source sources.list' and i get error msgs 
about the 'deb' commands.
* root@marc-desktop:/etc/apt# source sources.list
No command 'deb' found, did you mean:
 Command 'debc' from package 'devscripts' (main)
 Command 'derb' from package 'libicu-dev' (main)
 Command 'dab' from package 'bsdgames' (universe)
 Command 'debi' from package 'devscripts' (main)
deb: command not found
deb-src: command not found

Thanks for any help.

You can still build everything using Java 1.6. I won't say it won't crash, but 
I have compiled it with Java 1.6 and it works for me.

Just hardcode the java_version and javac_version in build/core/main.mk and it 
will work.

e.g. change "javac_version := $(shell javac -version 2>&1 | head -n 1 | grep '[ 
"]1\.5[\. "$$]')" to 'javac_version := "1.5"'

This is not recommended though.

Cheers,
  Raphael.

Same here. I was able to change the required Java version to 1.6 which is the 
default on Fedora 13+ and there were no issues with the build & install process.
