@Init methods are not properly called when more than one method with the same number of parameters

When there is more than one @Init method with the same number of parameters (>=1) then it is possible that the wrong @Init method is called.
The patch also makes the test more powerful (considering inhertance etc).

Posting a reply to my own question again, the assesment above was somewhat incorrect. However, as patch in ejb3 module, org.jboss.ejb3.stateful, the code for the method getInitParameters should be replaced with

protected Object[] getInitParameters(Method method, Class[] initParameterTypes, Object[] initParameterValues)
{
if (method.getParameterTypes().length == initParameterTypes.length)
{
for (int i = 0; i < initParameterTypes.length; ++i)

{ Class formal = method.getParameterTypes()[i]; Class actual = initParameterTypes[i]; if (!isMethodInvocationConvertible(formal,actual==null?null:actual)) return null; }

return initParameterValues;
}
return null;
}

/**
