I tested the latest nightly build; the behavior is unchanged.
**Build tested**: `apache-storm-3.0.1-SNAPSHOT.tar.gz` from
nightlies.apache.org (Last-Modified 2026-09-03 01:00 GMT), on Temurin 25.
**Result**: still reproduces. Two independent single 27-byte frames (a
tuple referencing an unregistered class), two worker kills.
Each time:
- `IllegalArgumentException: Class is not registered` from
`Kryo.getRegistration` via `KryoTupleDeserializer`, on the netty server
thread (`StormServerHandler.channelRead`)
- `Received error in netty thread.. terminating server...` → the worker
exits (code 20) after ~3s via the `Halting after 3 seconds`
shutdown hook, and the supervisor relaunches it
- No `Swallowing` lines in the logs and the process actually dies, so it is
neither the tolerated-skip nor the reset-but-alive path.
I also disassembled the shipped `storm-client-3.0.1-SNAPSHOT.jar`:
`StormServerHandler.ALLOWED_EXCEPTIONS` still contains only
`IOException`, matching the observed behavior.
I can share the payloads, worker logs, and environment details if useful.
