Who are the "Jews of my Community" that the Messenger of Allah (peace and blessings be upon him) warned against, saying: "Beware of the Jews of my Community"?

We have not come across a hadith with this exact wording. However, there is another hadith close to it: "Give greetings of peace to the Jews and Christians, but do not give greetings of peace to the Jews of my Ummah." It was asked, "And who are the Jews of your Ummah?" He said, "One who abandons prayer."
