Summary: Make loadClass thread-safe for class loaders of Connect plugins Key: KAFKA-6277 URL: https://issues.apache.org/jira/browse/KAFKA-6277 Project: Kafka Issue Type: Bug Components: KafkaConnect Affects Versions: 0.11.0.2, 1.0.0 Reporter: Konstantine Karantasis Assignee: Konstantine Karantasis Fix For: 1.0.1, 0.11.0.3 In Connect's classloading isolation framework, {{PluginClassLoader}} class encounters a race condition when several threads corresponding to tasks using a specific plugin (e.g. a Connector) try to load the same class at the same time on a single JVM. The race condition is related to calls to method {{defineClass}} which, contract to {{findClass}}, is not thread safe for classloaders that override {{loadClass}}.
