Hello, I noticed that each ActionHandler is loaded by a different instance of ProcessClassLoader. Incidentally that means that static variables cannot be used, as static variables are classloader-scoped. The code responsible for this is in ClassLoaderUtil.java public static ClassLoader getProcessClassLoader(ProcessDefinition processDefinition) { | return new ProcessClassLoader(ClassLoaderUtil.class.getClassLoader(), processDefinition); | } A new instance everytime, instead of a singleton... Is this behaviour by design ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074787#...
