> Some of the test XLang transforms (CoGroupByKey, MultiInputOutput, and Partition) fail on the Go SDK (using the Java Test Expansion Service). These tests used to pass and started failing at some point for unknown reasons.
> The failures tend to involve a ClassNotFound exception, like so:
> {noformat}
> RuntimeError: java.lang.IllegalArgumentException: unable to deserialize Custom DoFn With Execution Info
> at org.apache.beam.sdk.util.SerializableUtils.deserializeFromByteArray(SerializableUtils.java:78)

> Edit: This seems to be due to artifact staging issues. This bug has been re-titled to be more accurate to the root cause.
