Jeffrey Jones, who played irate Principal Rooney in Ferris Bueller's Day Off, pleaded guilty in a sex offender case in L.A. on Tuesday.

TMZ reports that the actor -- who turned 64 Tuesday -- admitted in court to failing to update his sex offender registration. Back in 2003, Jones pled no contest after he paid a minor with the intent of taking sexually explicit photos.

After that plea, Jones was required to register annually as a sex offender; he didn't register in 2009, and was subsequently arrested.

In exchange for his guilty plea on Tuesday, Jones avoids 3 years in a state prison. Instead, he'll serve 3 years formal probation and complete 250 hours of community service in a roadside clean-up program.

In addition to 1986's Ferris Bueller, Jones' 60-plus film credits include Tim Burton's Sleepy Hollow (1999), Amadeus (1984) and Keanu Reeves flick The Devil's Advocate (1997).
