-----------------------------------------
Summary: Storm-kafka tests leak resources due to retained
references to KafkaServer
Key: STORM-1756
URL: https://issues.apache.org/jira/browse/STORM-1756
Project: Apache Storm
Issue Type: Bug
Components: storm-kafka
Reporter: Stig Rohde Døssing
Assignee: Stig Rohde Døssing
Since JUnit keeps a reference to each test class until all tests for a module
have run, the KafkaTestBroker fields are not eligible for garbage collection
until all tests have run. KafkaTestBroker keeps a reference to
KafkaServerStartable/KafkaServer, which allocates resources that are also not
eligible for collection. This very quickly causes surefire to run out of memory
if this class is used more than a few places.
