Yes, I am using Tomcat. The problem is that I have a custom classloader
called LocalClassLoader and is conflicting with WebAppClassloader, and both
are loading DefaultTipology.class from WEB-INF\classes.
I had the same problem using XStream, but XStream has the posibility to set
the classloader.
ClassLoader classLoader = DefaultTipology.class.getClassLoader();
xstream.setClassLoader(classLoader);
The solution I am thinking is to modify some graffito files, for example
ReflectionUtils.java , and change Class.forName(className) into
Class.forName(className, classloader).
Maybe I can contribute with Graffito with this extra feature, what do you
think?
