             Summary: Fix Thrift/Dozer incompatibilty in Java 11
                 Key: AIRAVATA-3328
                 URL: https://issues.apache.org/jira/browse/AIRAVATA-3328
             Project: Airavata
          Issue Type: New Feature
          Components: Registry API
            Reporter: Marcus Christie
            Assignee: Marcus Christie


Thrift required fields can have a default value. This value is present in the generated models, but it is only serialized if the field has actually been set. The semantics on required fields with default values seems a little confusing.

This causes an issue with Dozer since it has logic to only copy fields when they differ. A field on an entity will only copy to a Thrift data model field when they have the same value. If the field on the entity has the default value of the Thrift field, then it won't copy and that field will not get serialized. This then causes a validation error in Thrift since the required field wasn't set.

This problem was initially discoverred in AIRAVATA-3268, see [this comment](https://issues.apache.org/jira/browse/AIRAVATA-3268?focusedCommentId=16978768&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16978768) and following.

I think, as noted in [this comment](https://issues.apache.org/jira/browse/AIRAVATA-3268?focusedCommentId=16979609&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16979609), that we can create a [Dozer Custom Bean Factory](https://dozermapper.github.io/gitbook/documentation/custombeanfactories.html) to fix this.
