see following part in stack trace:
caused by: java.lang.classnotfoundexception: com.fasterxml.jackson.core.jsonparseexception @ java.net.urlclassloader$1.run(unknown source) ... it suggests error caused class jsonparseexception of package com.fasterxml.jackson.core jvm tried load not find not in classpath.
just add com.fasterxml.jackson.core jar file in classpath.
