> In <3.6.0-rc0, duplicates of a plugin would be shown if it subclassed
> multiple interfaces. For example:
> {noformat}
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter"
> },
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter"
> },{noformat}
> In 3.6.0-rc0, there are many more listings for the same plugin. For example:
> {noformat}
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter"
> },
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter"
> },
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter"
> },
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter"
> },
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter"
> },
> {
> "class": "org.apache.kafka.connect.storage.StringConverter",
> "type": "converter",
> "version": "3.6.0"
> },{noformat}
> These duplicates appear to happen when a plugin with the same class name
> appears in multiple locations/classloaders.
> When interpreting a connector configuration, only one of these plugins will
> be chosen, so only one is relevant to show to users. The REST API should only
> display the plugins which are eligible to be loaded, and hide the duplicates.
