From 40b5be4ba243aaea1c45594c127b18e6ea363880 Mon Sep 17 00:00:00 2001 From: "Mark S. Lewis" Date: Mon, 13 Nov 2023 11:56:33 +0000 Subject: [PATCH] Allow schema types with the same name from different packages Previously the short type name was used as a schema key. This meant that types of the same name from different packages would overwrite each other in the map of schema type definitions, causing unexpected serialization errors. Now the fully qualified (package + type) name is used so that entries for types with the same name from different packages are unique. Signed-off-by: Mark S.
