Note: the full stack trace of the root cause is available in the Apache Tomcat/7.0.12 logs.

I included all the jars, and still I am not able to hit the point of error.

I am also getting the same Error that is related to ClassVisitor of ASM library.

I found a solution by adding asm-3.1.jar for jersey 1.17.1 version that is available from this link .

That solved the above error for me.

I just found the answer in case somebody else runs into the same pb: I installed jersey from the bundle. But the bundle is lacking asm lib. So I downloaded the zip jersey instead which contains the asm lib and it worked. :)
