ECJ is a binary blob, and you need some pre-compiled Classpath binaries. For GNU Guix we bootstrap the JDK with Jikes, SableVM, various versions of GNU Classpath, and an older version of ECJ built from source. The details can be found here: http://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/java.scm#n68 GCJ was no good bootstap compiler as it included a pre-built copy of Classpath. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
