### Describe the bug, including details regarding any error messages, version, and platform. We are retrieving data from Dremio server using Arrow Flight SQL client: ```java for (final FlightEndpoint endpoint : flightInfo.getEndpoints()) { try (FlightStream stream = flightSqlClient.getStream(endpoint.getTicket(), options)) { while (stream.next()) { ... } } ``` On x86 architecture it works fine, but on s390x platform it fails with: ``` Caused by: java.lang.IndexOutOfBoundsException: index: -3690987520, length: 4 (expected: range(0, 808)) at org.apache.arrow.memory.ArrowBuf.checkIndexD(ArrowBuf.java:320) at org.apache.arrow.memory.ArrowBuf.chk(ArrowBuf.java:307) at org.apache.arrow.memory.ArrowBuf.getInt(ArrowBuf.java:426) at org.apache.arrow.vector.BaseVariableWidthVector.getStartOffset(BaseVariableWidthVector.java:1314) at org.apache.arrow.vector.BaseVariableWidthVector.setReaderAndWriterIndex(BaseVariableWidthVector.java:398) at org.apache.arrow.vector.BaseVariableWidthVector.setValueCount(BaseVariableWidthVector.java:986) at org.apache.arrow.vector.complex.ListVector.setValueCount(ListVector.java:940) at org.apache.arrow.vector.complex.DenseUnionVector.setChildVectorValueCounts(DenseUnionVector.java:1322) at org.apache.arrow.vector.complex.DenseUnionVector.setValueCount(DenseUnionVector.java:1310) at org.apache.arrow.vector.VectorSchemaRoot.setRowCount(VectorSchemaRoot.java:240) at org.apache.arrow.vector.VectorLoader.load(VectorLoader.java:86) at org.apache.arrow.flight.FlightStream.next(FlightStream.java:270) ``` ### Component(s) Java -- This is an automated message from the Apache Git Service.
