Review Comment:
Since the method `throws IOException`, I don't think it's necessary to
convert it to `RuntimeException`. (In cases where conversion is needed, prefer
the more specific `UncheckedIOException`.)

Review Comment:
Let's rely on auto-close:
```suggestion
int bytesPerCRC;
long crcPerBlock;
try (DataInputBuffer buffer = new DataInputBuffer()) {
buffer.reset(bytes, 0, bytes.length);
bytesPerCRC = buffer.readInt();
crcPerBlock = buffer.readLong();
}
```
