URL: https://github.com/apache/arrow-java/issues/49
## Describe the bug, including details regarding any error messages,
version, and platform.
I run Arrow's demo codes under JDK8 and Arrow 17.0.0, but it seems not work.
IPC reader example code as below:
`
try(
BufferAllocator allocator = new
RootAllocator(Long.MAX_VALUE);
FileInputStream fileInputStream = new FileInputStream(new
File("random_access_file.arrow"));
ArrowFileReader reader = new
ArrowFileReader(fileInputStream.getChannel(), allocator);
){
System.out.println("Record batches in file: " +
reader.getRecordBlocks().size());
for (ArrowBlock arrowBlock : reader.getRecordBlocks()) {
reader.loadRecordBatch(arrowBlock);
VectorSchemaRoot root = reader.getVectorSchemaRoot();
System.out.println("VectorSchemaRoot read: \n" +
root.contentToTSVString());
}
} catch (IOException e) {
e.printStackTrace();
}
`
