commit 1e3bc4c3b34eae563547899645bfb3f0a1948c79 Author: Doug Rohrer <[email protected]> AuthorDate: Thu May 18 20:44:43 2023 -0400 Add JMX utility class to in-jvm dtest to ease development of new tests using JMX While reviewing CASSANDRA-18511, some repetitive code was identified across the 4 branches, and 2 different tests, that would also be repeated for any new usages of the JMX support in the in-jvm dtest framework. Therefore, a utility class should be added to the dtest-api's `shared` package that will simplify some of this repetitive and error-prone code. patch by Doug Rohrer; reviewed by Jon Meredith, Dinesh Joshi for CASSANDRA-18537 --- .../cassandra/distributed/shared/JMXUtil.java | 53 ++++++++++++++++++++++ 1 file changed, 53 insertions(+) diff --git a/src/main/java/org/apache/cassandra/distributed/shared/JMXUtil.java b/src/main/java/org/apache/cassandra/distributed/shared/JMXUtil.java new file mode 100644 index 0000000..183397e --- /dev/null +++ b/src/main/java/org/apache/cassandra/distributed/shared/JMXUtil.java @@ -0,0 +1,53 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
