apache orc reader close

Question

I'm using org.apache.orc.OrcFile.createReader This lib is fine to read Orc files but I don't find any close method. Is it normal?

val fic=OrcFile.createReader(new Path(element), OrcFile.readerOptions(conf));
val  rows:RecordReader = fic.rows();
        while (rows.nextBatch(batch)) {
          println ("number of rows"+batch.size) 
        }
// fic.close ??
