Debug Jackson with Spring

I just wrote some code in multiple files in my Spring REST API and I have Jackson errors now.

org.springframework.context.ApplicationContextException: Unable to start 

embedded container; nested exception is

I can't find what the error is and none of my files are specified in the error. Is there a way to get a better Jackson error output? I know you can't really help without the code but there are too many classes to put everything here.

I have this dependency for jackson in my pom.xml, I'm unsure which version it is.

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-joda</artifactId>
 </dependency>

I found this using Swagger, with spring mvc as the server type, I found the error to be in application.properties as generated by swagger...

springfox.documentation.swagger.v2.path=/api-docs
server.contextPath=
server.port=8080
spring.jackson.date-format=io.swagger.RFC3339DateFormat
spring.jackson.serialization.WRITE_DATES_AS_TIMESTAMPS=false

In my case the 'i' in the error

aused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.http.converter.json.Jackson2ObjectMapperBuilder]: Factory method 'jacksonObjectMapperBuilder' threw exception; nested exception is java.lang.IllegalArgumentException: Illegal pattern character 'i' at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate

Was a result of the io.swagger.RFC3339DateFormat

I am currently experiencing this problem, and at least removing that line gives me a new and different error...at least it's a breadcrumb.

I had a similar issue. In my case, it turned out that the date format class was being generated in a different directory. I had to update the the default entry in application.properties to

spring.jackson.date-format=com.company.date.RFC3339DateFormat
