Doug Rohrer commented on CASSANDRA-18725:
-----------------------------------------
So far seeing nothing but known jvm-dtest failures in Circle. Given the changes
are isolated to the in-jvm dtest framework I'm focusing on those failures as it
shouldn't touch anything else.

Rerunning J17 as CircleCI said there was an infrastructure failure somehow -

> Key: CASSANDRA-18725
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18725
> Project: Cassandra
> Issue Type: Improvement
> Components: Test/dtest/java
> Reporter: Doug Rohrer
> Assignee: Doug Rohrer
> Priority: Normal
> Fix For: 3.11.x, 4.0, 4.1.x, 5.0, 5.1
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> In the original implementation of the JMX feature, we fixed some memory leaks
> by clearing some internal state in Java’s TCPEndpoint. However, that
> implementation was overly aggressive and cleared the whole map, vs. just
> removing the endpoints created by the individual instances. This causes
> issues when you remove a node from the cluster (as all of the endpoints are
> cleared, not just the ones in use by that instance).
>
> In stead, we should check if the endpoint was created by the instance in
> question and only remove it if it was.
