As a Jewish man I can tell you this. Most Jewish people can handle a good Jew joke.
Case and point:
Why does the Jew do after one of his friends leaves?
He checks the sofa for loose change.
However, Hitler cracks, just aren't funny, period. And usually when people are called out on them, some debate about what a smart mis-understood leader he was is sparked by the joke cracker.
