Is there anything tricky I should know about `instanceof`? I'm passing a list of objects through a few methods and testing whether these objects implement a particular interface using `instanceof`. In some cases, `instanceof` correctly identifies objects as implementing the interface, in other cases it doesn't. It appears to be giving me inconsistent results on the same object in different places. Is there any trick/gotcha I should be aware of here?
In anticipation of comments you might have:
1) I know `instanceof` is bad form. I'm working with a less-than-perfect object hierarchy that can't be changed, and this is the least bad thing I can think to do.
2) I'm working to create a code example, but I'll need to simplify my code a lot if I'm going to paste in anything useful here. In the meantime, if you've seen this before and can shed some light, please do. Any chance of getting a code sample?
