Narrative:
Crossing the byp VOR and turning to the outbound radial, controller gave us an additional 10 degrees left for traffic. When we rolled out at 11000 ft, a 210 degree heading at karla intersection, TCASII announced monitor vertical speed and a target popped up at 12 O'clock and 5 mi, 500 ft below us. Target was a cessna jump plane turning towards us in a l-hand turn being worked by ZFW. Jump plane called and said he would climb and the controller responded with a don't climb. TCASII gave us an RA with traffic 2 mi at 12 O'clock, 400 ft below and climbing. First officer, flying, pulled up in a gentle climb and I advised ATC we were responding to an RA. Controller said that traffic was no longer a factor. We had visual contact on the cessna and flew directly over him. Had we not climbed, we would have passed within 300-400 ft above him. Why does the FAA allow jump activity directly on an arrival within 500 ft of same? Why, if the controller is working the traffic, does he allow them to operate in this airspace? This is an accident waiting to happen.

Title: RPTED NMAC BTWN AN ACR MD80 AND A CLBING JUMP ACFT WHO WAS TOLD BY THE CTR CTLR NOT TO CLB. ACR CLBED AND PASSED OVER THE CESSNA AFTER RESPONDING TO A TCASII RA.
Narrative: XING THE BYP VOR AND TURNING TO THE OUTBOUND RADIAL, CTLR GAVE US AN ADDITIONAL 10 DEGS L FOR TFC. WHEN WE ROLLED OUT AT 11000 FT, A 210 DEG HDG AT KARLA INTXN, TCASII ANNOUNCED MONITOR VERT SPD AND A TARGET POPPED UP AT 12 O'CLOCK AND 5 MI, 500 FT BELOW US. TARGET WAS A CESSNA JUMP PLANE TURNING TOWARDS US IN A L-HAND TURN BEING WORKED BY ZFW. JUMP PLANE CALLED AND SAID HE WOULD CLB AND THE CTLR RESPONDED WITH A DON'T CLB. TCASII GAVE US AN RA WITH TFC 2 MI AT 12 O'CLOCK, 400 FT BELOW AND CLBING. FO, FLYING, PULLED UP IN A GENTLE CLB AND I ADVISED ATC WE WERE RESPONDING TO AN RA. CTLR SAID THAT TFC WAS NO LONGER A FACTOR. WE HAD VISUAL CONTACT ON THE CESSNA AND FLEW DIRECTLY OVER HIM. HAD WE NOT CLBED, WE WOULD HAVE PASSED WITHIN 300-400 FT ABOVE HIM. WHY DOES THE FAA ALLOW JUMP ACTIVITY DIRECTLY ON AN ARR WITHIN 500 FT OF SAME? WHY, IF THE CTLR IS WORKING THE TFC, DOES HE ALLOW THEM TO OPERATE IN THIS AIRSPACE? THIS IS AN ACCIDENT WAITING TO HAPPEN.
