The former captain was a certainty to feature at the 2007 tournament until injury struck, although some would argue that the disappointment served Jones well as he missed the humiliation of a first-round exit following the defeat to Fiji in Nantes.
It looked as though his injury jinx may have struck again when a calf problem saw him miss the warm-up wins over England and Argentina, but he was yesterday handed a place in Warren Gatland's final 30-man party.
Jones expects to be fit for Wales' vital Pool D opener against South Africa in Wellington on September 11, and the 30-year-old cannot wait to be involved in the game's global showpiece.
He said: "I was over the moon yesterday when I got confirmation that I am on the plane.
"It was such a great day and it's something I always dreamed of doing and I am looking forward to.
"I can't stress enough how important and special this is to me and my family.
"Everyone speaks so fondly of it and New Zealand is a fantastic place to go and play.
"They have had some tough times out there with the recent natural disasters, but there will be such a warm reception.
"Rugby is such a special sport and we want to give something back to them and hopefully the public will embrace it."
The Ospreys forward, who will also provide a second-row option for Gatland in New Zealand, was desperate to be involved, but decided against sitting in front of the television to find out if he had made the cut.
"I went and had lunch with my wife in Monmouth yesterday. We had a day out," he said.
"It was more escapism for me, to be honest. I didn't watch the telly or listen to it. I waited for my dad to text to say if I was in or not, so we could have ended up commiserating instead of celebrating.
"But you hope you have done enough over the recent weeks, and previous to that, to put yourself in the best possible position."
The calf injury picked up by Jones was among several that have dogged Wales' build-up.
Stephen Jones, Rhys Priestland and Gethin Jenkins have all suffered similar problems in recent weeks but made the final cut.
And Jones says he will be fit and raring to go come the critical encounter with the Springboks.
"It's fine," he said. "The recovery has been a bit slower than I hoped but I'm feeling pretty good. We have a lighter week ahead as we want to build it up slowly, so it feels pretty good."
Wales will have to improve on a record against South Africa that has seen them beat the reigning world champions just once in 25 attempts.
Gatland's side were guilty of throwing away handy leads on the two occasions the teams met in 2010, and Jones hopes those experiences can help Wales going forwards.
He said: "It is a frustration as we have run them pretty close but have not been able to turn them over.
"But it's a World Cup and special things happen in World Cups. They will go in as favourites, but not huge favourites, so we have everything to play for and it's a massive opener.
"It's such a tough group (also including Samoa, Fiji and Namibia) we are in but we have to thrive on that and try to come away with a win, even if we win all four games 3-0."
