Done. Docbooks should build now using Sun JRE 1.4 or any 1.5 JRE. Also note that building the UIMA assembly (calling mvn assembly:assembly) calls the docbooks build and so you have to be using the right JRE here too.

For the curious... The reason is because IBM's Java bundles Xerces already. So adding xercesImpl.jar to the classpath just adds classes with the same class names as those already bundled in the JRE. The -D argument cannot be used to distinguish them. The ones in the JRE take precedence. About the only way I could think to work around this would be to go into your JRE install directory and remove xml.jar. But it's probably better to just not use this buggy JRE at all. Sun's Java bundles a different XML parser with different class names, and doesn't have this problem. Also in Java 5 they finally realized this problem and renamed the XML parser classes when bundling them, so that they can be overridden. -Adam
