But compile-time weaving is supported, says the 1.5.6 documentation. On my 3.2.7 with 1.5.6GA with JDK 1.4, I followed the install instructions, I get java.lang.NoClassDefFoundError: org/jboss/mx/loading/RepositoryClassLoader before it even gets to my ear file. That class in in JBoss 4, not 3. I understand if you don't want to support JBoss 3 any more but then don't claim you do in the documentation.
