The best thing would be if I could just "sudo apt-get install ecj".  If 
there are any differences between ecj and ecj1, we should provide some 
kind of wrapper.  A nice possibility, would be to support dropping the 
downloaded JAR somewhere in the tree where it installs correctly and 
automagically.  This would not be against the SC decision.

Cool, though not unexpected because the code generation of Java 
bytecodes is not that hard (apart from the unreachable and uninitialized 
code checking).
