hellishfire opened a new issue, #41682:
URL: https://github.com/apache/arrow/issues/41682

   ### Describe the bug, including details regarding any error messages, 
version, and platform.
   
   Reproduced on latest arrow release (16.0)
   
   When importing a sliced RecordBatch from c to java
   
   On c side:
   auto sliced_record_batch = original_record_batch->Slice(/*offset=*/8, 
/*length=*/2);
   arrow::ExportRecordBatch(sliced_record_batch, arrow_array_ptr);
   
   On java side:
   ArrowArray arrowArray = ArrowArray.allocateNew(allocator);
   Data.importIntoVectorSchemaRoot(allocator, arrowArray, vectorSchemaRoot, 
null);
   
   The imported vectorSchemaRoot maintains the correct length(which is 2), but 
the offset info (which is 8) is not respected, hence the content of the 
imported vectorSchemaRoot points to the first 2 rows of the 
original_record_batch.
   
   I'm not familiar with arrow code, but it seems that the offset info is 
actually present in org.apache.arrow.c.ArrowArray.Snapshot, but 
org.apache.arrow.c.ArrayImporter ignores the offset in 
org.apache.arrow.c.ArrayImporter.doImport(ArrowArray.Snapshot)
   
   
   ### Component(s)
   
   Java
