Fixes https://github.com/spring-projects/spring-integration/issues/3541 * Fix `DefaultConfiguringBeanFactoryPostProcessor` to check for `jsonPath` bean a `com.jayway.jsonpath.JsonPath` on CP instead of `JsonPathUtils` which is always there since it is a part of `spring-integration-core` * Remove `json-path` and `jackson-databind` from tests classpath to be sure that we have coverage for the mentioned above option classpath entries * Add `json-path` and `jackson-databind` into test classpath whenever it is necessary
