> The error progress message in {{RepairRunnable}} is not compliant with the {{LegacyJMXProgressSupport}} class, which uses a regex to match on the text of a progress event. Therefore, actual failures slip through as successes if using legacy JMX for repairs.
> In {{RepairRunnable}}
> {code}
> protected void fireErrorAndComplete(String tag, int progressCount, int totalProgress, String message)
> {
> fireProgressEvent(tag, new ProgressEvent(ProgressEventType.ERROR, progressCount, totalProgress, message));
> fireProgressEvent(tag, new ProgressEvent(ProgressEventType.COMPLETE, progressCount, totalProgress, String.format("Repair command #%d finished with error", cmd)));
> }
> {code}
> Note the {{"Repair command #%d finished with error"}}
> See https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/repair/RepairRunnable.java#L109
> In {{LegacyJMXProgressSupport}}:
> {code}
> protected static final Pattern SESSION_FAILED_MATCHER = Pattern.compile("Repair session .* for range .* failed with error .*");
> protected static final Pattern SESSION_SUCCESS_MATCHER = Pattern.compile("Repair session .* for range .* finished");
> {code}
> See https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/utils/progress/jmx/LegacyJMXProgressSupport.java#L38
> Legacy JMX support was introduced for CASSANDRA-11430 (version 2.2.6) and the bug was introduced as part of CASSANDRA-12279 (version 2.2.8).
