Agreed - the trick is avoiding the direct reference to the factory
class.

Not if there's a direct reference to the factory class
.5 i actually experienced oome on redeploy with code
without any issues mentioned by your article. After we removed
singleton dependency it went away.

separate the singleton itself and the factory.
in the previous example:
pu
separate the singleton itself and the factory.
in the previous example:
public class ASingletonFactory{
private static ASingletonImpl instance = new ASingletonImpl();
public static AsingletonImpl getInstance(){
return instance;
}
}
public class ASingletonImpl{
ASingletonImpl()
So how should one write their singleton?
