I didn't. I looked at both versions of maven-jaxb-plugin at https://maven-repository.dev.java.net/repository/com.sun.tools.xjc.maven2/poms/and both have the odd characters in. There seem to be other implementations of the maven-jaxb-plugin around and I tried the ones I could find but got NPEs in maven. Not sure whether this is the version of the plugin, the version of jaxb or a real problem. I'm not that faimiliar with JAXB and what version works with what so I don't have a quick fix. Also tried upgrading my JDK but that didn't work either. Am already on Maven 2.0.6.
Happy to try any other ideas people have. What I have to do is work backwards through this and work out what version of what will actually work for us (I find trying to work this out for maven plugins very difficult) and see if I can get a combination that doesn't have the author name with the non-UTF8 character or where this particular fault has been fixed. Failing this we will have to get on whatever mail list deals with it and ask for a fix. As it stands we can offer a manual fix for anyone who has Linux/IBM JDK, i.e. run the build until it fails and then remove the problematic characters manually from the offending pom in the local repo. I can't say how long this will take but I think we need to get on with the release and address is next time. Simon
