it works like a charm, only -- unlike @Singleton -- it is not lazy (and if
turned to lazy, it would not be threadsafe).
there is an easy Java trick for lazy:
class Foo {
static getInstance() {
return Inner.instance
}
private Foo(){}
private static class Inner {
final static instance = new Foo()
}
}
The trick is that the inner class is only loaded if getInstance is
called, thus you get lazy behaviour, that is even thread safe.
