Thanks for posting the psuedo code.
>From the symptoms, the code you posted and the assumption that this
section of code is multi-threaded, it looks like a race condition.
public StaticClass {
private static Manager manager = new Manager();
public static Manager getManager() { return manager; }
}
If 2 Threads simultaneously access the above its possible that the 2nd
will receive a partially configured instance of Manager.
It's one of the reasons I avoid statics like the plague.
Try changing it to:
public StaticClass {
private static Manager manager = new Manager();
public static synchronized Manager getManager() { return manager; }
}
