Caused by: java.lang.IllegalArgumentException: Conflicting setter definitions for property "AttributeStatus": com.pkj.Clazz#setAttributeSource(1 params) vs com.pkj.Clazz#setAttributeStatus(1 params)

Symptoms :

1. You are using com.fasterxml.jackson.databind ObjectMapper
2. By using object of ObjectMapper you are possibly trying Convert Json to POJO
3. All problem lies in your POJO class

Solution:

1.  Go to your POJO class i.e. Clazz in my case
2. checkout the property or variable named "AttributeStatus"
3. In my case  I had added   @JsonProperty("AttributeSource") on two properties or variables
4. So corrected that and it worked, meaning I had put correct @JsonProperty on respective variables.

i.e. 

 Before

     @JsonProperty("AttributeSource") 

      private String AttributeSource

     @JsonProperty("AttributeSource") 

      private String AttributeDestination

After

     @JsonProperty("AttributeSource") 

      private String AttributeSource

     @JsonProperty("AttributeDestination") 

      private String AttributeDestination
