The getMethods in CtClass is not documented as being ordered, so I
peeked at the code and unless I'm looking at the wrong spot it comes
from an un-ordered HashMap.
public CtMethod[] getMethods() {
HashMap h = new HashMap();
getMethods0(h, this);
return (CtMethod[])h.values().toArray(new CtMethod[h.size()]);
}
I haven't tried to chase down what Tapestry is doing in transformed
classes, but I'm pretty sure counting on the undocumented ordering of
methods is a bad idea.
