However, the good news is that a new Java decompiler has come along to take its place - JD. I used this on Windows before, but I'm now on Fedora 11 and I never installed this new Java Decompiler there.
Thanks to Ian's blog, it took me less than 5 minutes to install the JD Java decompiler and its GUI front end (JD-GUI) on my F11 64-bit box. I had to issue this yum command, as per Ian's instructions, to get some libraries installed needed by JD-GUI:
yum install libcanberra-gtk2.i586 PackageKit-gtk-module.i586 gtk2-engines.i586
I then just un-tar'ed the JD-GUI download and it ran fine.
I also took the time to install the JD-Eclipse plugin for my Eclipse 3.5. That worked flawlessly on my first attempt.
So now I have a nice Java decompiler on my F11 box, both as a standalone GUI and as an Eclipse plugin.
