Francisco Guerrero created CASSANDRA-20335:
----------------------------------------------
Summary: Non-java types are leaking from snapshots
Key: CASSANDRA-20335
URL: https://issues.apache.org/jira/browse/CASSANDRA-20335
Project: Apache Cassandra
Issue Type: Bug
Reporter: Francisco Guerrero
https://issues.apache.org/jira/browse/CASSANDRA-18111 brought a major uplift of
the snapshot code. A new exception type was introduced for signaling issues
related to snapshots (\{{SnapshotException}}). This type however is leaking
through JMX. Cassandra only exposes java types through the RMI interface. I
encountered the issue in Sidecar when trying to create an already existing
snapshot. Here’s the stack trace:
