---------------------------------------
Summary: In-jvm dtest to detect InstanceClassLoaderLeaks
Key: CASSANDRA-19783
URL: https://issues.apache.org/jira/browse/CASSANDRA-19783
Project: Cassandra
Issue Type: Improvement
Components: Test/dtest/java
Reporter: Doug Rohrer
It is currently very easy to add dependencies/code that cause in-jvm dtest
{{InstanceClassLoader}} leaks, and hard to find them. These patches add a
WeakHashSet that allows us to count the number of reachable
InstanceClassLoaders in the in-jvm dtest API, so that we can use it in the
ResourceLeakTest in the actual Cassandra branches in CI (it only takes 2
iterations to find the leak recently introduced by the inclusion of the
{{oshi.jna }}library, which was fixed in
[https://github.com/apache/cassandra-in-jvm-dtest-api/pull/38])
