shunping opened a new pull request, #34615: URL: https://github.com/apache/beam/pull/34615
The original NullableCoder implementation incorrectly assumed its component coder was always length-prefixed (LP'd). In scenarios like a test `testFlattenMultipleCoders` using `Nullable[VarLong]`, the inner `VarLongCoder` is not LP'd. This decoder mismatch caused incorrect bytes to be read for the element, leading to incorrect buffer offsets. addresses #32930 Notice that the PR only fixes `org.apache.beam.sdk.transforms.FlattenTest.testFlattenMultipleCoders`. The fact that the other test `org.apache.beam.sdk.transforms.FlattenTest.testFlattenWithDifferentInputAndOutputCoders2` still fails implies a separate root cause. -- This is an automated message from the Apache Git Service.
