Is there a framework for synchronizing properties of POJOs? For example, I want to express (in some high-level, declarative form) that foo.text = bar.text + baz.text
or foo.y = (max(bars, y)).y
without having to register property change, element add and remove listeners on values and (especially) collections, which are repetitive and error-prone.

A:
javafx and it's bind operator. For example:
var x = 10;
var y = bind -x + 100;
assert y == 90; // passes
y = 40; // bind!
assert x == 60; // passes
for java take a look at JSR 295
