If you set the "-noverify" java option will result in the following exception and server startup
fails:

Problem is that -noverify is turning off early detection of classloading issues in the following
org.apache.xbean.recipe.ReflectionUtil code:

{code}
 static
  {
    String[] impls = { "org.apache.xbean.recipe.XbeanAsmParameterNameLoader", "org.apache.xbean.recipe.AsmParameterNameLoader"
};
    for (String impl : impls)
      try {
        Class loaderClass = ReflectionUtil.class.getClassLoader().loadClass(impl).asSubclass(ParameterNameLoader.class);
        parameterNamesLoader = (ParameterNameLoader)loaderClass.newInstance();
        break;
      }
      catch (Throwable ignored)
      {
      }
  }
{code}

With --noverify, the load of "org.apache.xbean.recipe.XbeanAsmParameterNameLoader" will succeed,
but fail later. Without --noverify (i.e. -verify), the load of "org.apache.xbean.recipe.XbeanAsmParameterNameLoader"
fails in the above load.
