2 more days spent on this, and I actually came up with a solution: Switching from JDK "modern" compiler to eclipse compiler. I found another thread about class transformation errors on the list, saying that the Java C compiler had issues with class transformation.
http://www.mail-archive.com/users@tapestry.apache.org/msg23610.html I rebuilt my classes with the eclipse compiler, and voila! No more errors about invalid constants and similar! The recipe for using eclipse compiler in ant: http://emacsblog.org/2007/02/13/emacs-jdee-ant-and-the-eclipse-java-compiler/ Regards Inge On Mon, Nov 2, 2009 at 3:00 PM, Inge Solvoll <inge.tapes...@gmail.com>wrote: > Done some pretty extensive research on this the last few days.
