Class clasecarga = Thread.currentThread()
                                    .getContextClassLoader()
                                    .loadClass("CompositeWithFormLayout");
Class[] classes = new Class[2];
classes[0] = Composite.class;
classes[1] = int.class;
Constructor constr = clasecarga.getConstructor(classes);
Object[] param = new Object[2];
param[0] = composite;
param[1] = new Integer(SWT.CENTER); // this was the problem
constr.newInstance(param);

The style CENTER is not a valid style for a Composite. The problems of
copy & 
paste :)
