It looks like the issue was caused by platform-inconsistent custom stacktrace serialization/deserialization at currently referenced 2.2.0 java client version (fixed by https://github.com/uber/cadence-java-client/pull/291) . Locally I've fixed it bumping client version to 2.5.0. Does it make sense to bump it here too?
