I think it is a similar problem, so not exactly the same.
I have a couple of pojo's inserted in Lists, these lists are added to the cache.
One of these pojo's have a state implemented using the GoF state pattern, hence
as pojo's theirselves.
Now when I change the state into a different state using
state = bindingFileState;
I get the following stack:

I have changed my code to
| if (!state.equals(bindingFileState)) {
| state = bindingFileState;
| } else {
| System.out.println("It's equal");
| }
| Which circumvents the problem, but I expected that an assignment, whether
or not with the same object would not case this stack trace.
Kind regards,
