Which version of ecj.jar is that?  I am using ecj.jar version 3.3 and it 
is only half that size (1,563,059 bytes).

I think that is the same case as reported to Eclipse here:
	https://bugs.eclipse.org/bugs/show_bug.cgi?id=166355

who AIUI decided it was a Sun javac bug that they did not want to replicate.

I usually use ECJ, but let me retry with the Sun compiler and I'll let 
you know how I get on.
