------- Comment #1 from bero at arklinux dot org 2006-08-15 23:02 ------- Some debugging shows this is related to the new jar -- if I use jar from gcc 4.1.x (or just fastjar 0.93 from www.sourceforge.net/projects/fastjar) to generate the ecj.jar file, I can binary-compile it with gcj 4.2 just fine (I also used gcj 4.2 to turn the .java files into .class files in both cases).
