JEdit will not start from either the command line or the Icon in the Applications ==> Programming menu.
As a footnote, my Dell Inspiron 9400 laptop (which has been running Ubuntu since Hardy) had a rocky upgrade to Natty 11.04 amd64 from Lucid 10.04 amd64, I had to chroot repair that one (may still have some issues)???

#/usr/bin/perl -wT

if (possible){
  use JEdit;
}

else{
  use Gedit;
}

Installed Oracle(Sun) Java and removed all openJDK JEdit works fine.

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

I encountered this, after having installed Sun JDK for an esoteric purpose.

Turns out I had somehow managed to install the "headless" (i.e. non-GUI) version of OpenJDK.

To fix:

$ sudo apt-get remove openjdk-7-jre-headless
$ sudo apt-get install openjdk-7-jdk

That made everything lovely for me.
