CHAIN-41 fix bad ant buildfile. Code now depends on digester1.8; the pom.xml had been updated but not the build.xml.
Thanks to Isaac Shabtay for the report.
Further fix for CHAIN-12 - Using JDK 1.4.2_10 ContextBase can be serialized, but JDK 1.4.2_11 (and 1.3.1_04) fail trying to serialize - thanks to Dennis Lundberg for spotting this.
