Before this change, validating the same unavailable connector plugin version twice could return a 500/NPE response instead of the normal validation result. Request: ``` http://localhost:8083/connector-plugins/org.apache.kafka.connect.file.FileStreamSinkConnector/config/validate { "connector.class": "org.apache.kafka.connect.file.FileStreamSinkConnector", "connector.plugin.version": "2.0.1", // unavailable connector plugin version "tasks.max": "1", "topics": "test" } ``` The second request will receive the following response: ``` { "error_code": 500, "message": "java.lang.NullPointerException: Cannot invoke \"java.util.List.stream()\" because the return value of \"org.apache.kafka.connect.runtime.isolation.VersionedPluginLoadingException.availableVersions()\" is null" } ``` -- This is an automated message from the Apache Git Service.
