      Description

      We now use Classpath 0.95 as our default. Classpath 0.95 has a build option of --with-javac meaning it can be compiled without ecj, this means we can remove downloading ecj from our build. There's a possible issue in that the Classpath build may run out of memory with javac, so we may need to run the Classpath configure with --with-javac="javac -J-Xmx512M -target 1.5".

            A related note, ecj 3.3 has just been released so we can bump:
            "http://download.eclipse.org/eclipse/downloads/drops/R-3.2-200606291905/ecj.jar"
            in builds/components/ecj.xml to:
            "http://fullmoon.torolab.ibm.com/downloads/drops/R-3.3-200706251500/ecj.jar"

            With Classpath 0.96.1, just --with-javac should be sufficient as the memory requirement will be automatically dealt with if the javac found supports that option.

            Currently we are downloading Classpath 0.97 but compiling with ecj 3.2. We need the ecj dependency because:

            • all JDK 1.5s can't compile Classpath 0.97 due to a bug in javac, in particular our PowerPC set ups are relying on JDK 1.5 VMs awaiting a more stable 1.6 VM release
            • the ecj that is installed on Fedora and OpenSuSE, by default, is the broken 3.3.0 version that creates a broken Classpath
