Read some Star Wars novels, and you'll see. You know when Grievious was spinning his lightsaber? Something like that except a jedi does it to deflect big heavy rounds, however there's a big possibility of a light blaster bolt to get into a spot where the lightsaber isn't at yet in the spinning phase, so it can penetrate it.

It's from the ROTS game..... 😆
Anyway, I don't think all jedi can (however, any jedi should be able to do it with the force, just stop the bullets in their trail). Luke by NJO for example, should easily doing it, seeing as his saber looks like 20, and he can move faster than a bullet just in pure speed.....
