Description

During Circle CI runs there are some flaky integration tests, some noticed are

• HostReplacementMultiDCTest
• HostReplacementMultiDCFailureTest
• HostReplacementFailureTest
• LeavingSingleFailureTest

Some of the error message I see in these tests are e.g.

java.lang.RuntimeException: java.lang.IllegalStateException: Can't load org.apache.cassandra.utils.concurrent.Ref$OnLeak. Instance class loader is already closed.

On repeated run, these tests pass.
