[jira] [Commented] (CALCITE-1475) Jackson shading causes JsonIgnore
to be ignored when serializing response as JSON
[ https://issues.apache.org/jira/browse/CALCITE-1475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15617608#comment-15617608 ]
Julian Hyde commented on CALCITE-1475:
--------------------------------------
[~elserj], Any thoughts on this? Do you think my diagnosis is correct? Since Avatica has been shading for a while, I'm surprised it has only just come to light. And, I wonder whether there is any workaround that would allow Calcite to work on Avatica as it stands.

> I am getting an error while running {{CalciteRemoteDriverTest.testRemotePrepareExecute}} because Avatica is trying to serialize the field {{CalcitePrepare.CalciteSignature.rowType}} to JSON. The field has the annotation {{@JsonIgnore}} but I surmise that that annotation is being ignored because Jackson is being shaded inside Avatica.
