Are you referring to java.net.Proxy? Proxy.equals depends on the resolution of its address. Address resolution could change over time, depending on the caching policy. java.net.URL has a similar issue.

Strangely,I would have expected containsValue and containsKey to behave in a similar fashion. I think the specification for these methods is very clear, they should use equals(). I'm not sure if containsKey is correct if it accepts key equality. -Chris I assume he is talking about java.lang.reflect.Proxy as it forwards the hashCode and equals methods to the invocation handler.
