Description

OverWindow and Window are confusing in the API, and mentioned that we want to rename it to GroupWindow for many times.  So,  here just a suggestion, how about Deprecated the Window in release-1.8, since we should create a new RC2 for release 1.8. If we do not do that the Window will keep existing for almost half a year. I create this JIRA, and link to release-1.8 vote mail thread, ask RM's options. If all of you do not agree, I'll close the JIRA, otherwise, we can open the new PR for Depercated the window.
What do you think?
