Describe the bug
List#contains performs a linear search, which could have performs implications if the list is large and called repeatedly.

To Reproduce
See code

Expected behavior
A performant implementation.

Additional context
Review usage to see if a HashSet would be more appropriate in this context.

opentracing-concurrent is used in tests therefore should be removed from opentracing-jaxrs2
