As you can see, this bit of code comes from Pellet. I have not used Pellet and Jena in a long time so my knowledge might be rusty, but it appears that Pellet comes with its version of Jena and you also have another version of Jena in the classpath; the two versions are not compatible and that's the origin of this error. Remove one version and leave the other - I would keep the one that comes with Pellet. HTH, I.
