I read codes of

DimensionManager

and find a field

weakWorldMap

. It's a weak map and when

setWorld

a world object is put in and they are never removed. I doubt whether this would cause memory leak after several loading and unloading operations, since weak maps determine equality by

==

not

.equals

. And want to know what the field used for.

 

That's my question. Any reply would help. Thank you.

I think it is for checking leaked worlds, which means that the world is not used.

It seems to be for purely debugging purpose.

Thanks.

I found out that since it's a weak map, its values can be released by gc mechanism.
