Buggy source:
public static FileTermination checkTermination(final File file) throws IOException {
  final long fileSize=file.length();
  if (fileSize < BlockCompressedStreamConstants.EMPTY_GZIP_BLOCK.length) {
    return FileTermination.DEFECTIVE;
  }
  final RandomAccessFile raFile=new RandomAccessFile(file,"String_Node_Str");

  byte[] buf=new byte[BlockCompressedStreamConstants.EMPTY_GZIP_BLOCK.length];

    byteBuffer.order(ByteOrder.LITTLE_ENDIAN);
    final int totalBlockSizeMinusOne=byteBuffer.getShort() & 0xFFFF;
    if (buf.length - i == totalBlockSizeMinusOne + 1) {

    }

Fixed version (ground truth):

  final long fileSize=file.length();
  if (fileSize < BlockCompressedStreamConstants.EMPTY_GZIP_BLOCK.length) {
    return FileTermination.DEFECTIVE;
  }
  final RandomAccessFile raFile=new RandomAccessFile(file,"String_Node_Str");
  try {
    raFile.seek(fileSize - BlockCompressedStreamConstants.EMPTY_GZIP_BLOCK.length);
    byte[] buf=new byte[BlockCompressedStreamConstants.EMPTY_GZIP_BLOCK.length];
    raFile.readFully(buf);
    if (Arrays.equals(buf,BlockCompressedStreamConstants.EMPTY_GZIP_BLOCK)) {
      return FileTermination.HAS_TERMINATOR_BLOCK;
    }
    final int bufsize=(int)Math.min(fileSize,BlockCompressedStreamConstants.MAX_COMPRESSED_BLOCK_SIZE);
    buf=new byte[bufsize];
    raFile.seek(fileSize - bufsize);
    raFile.read(buf);
    for (int i=buf.length - BlockCompressedStreamConstants.EMPTY_GZIP_BLOCK.length; i >= 0; --i) {
      if (!preambleEqual(BlockCompressedStreamConstants.GZIP_BLOCK_PREAMBLE,buf,i,BlockCompressedStreamConstants.GZIP_BLOCK_PREAMBLE.length)) {
        continue;
      }
      final ByteBuffer byteBuffer=ByteBuffer.wrap(buf,i + BlockCompressedStreamConstants.GZIP_BLOCK_PREAMBLE.length,4);
      byteBuffer.order(ByteOrder.LITTLE_ENDIAN);
      final int totalBlockSizeMinusOne=byteBuffer.getShort() & 0xFFFF;
      if (buf.length - i == totalBlockSizeMinusOne + 1) {
        return FileTermination.HAS_HEALTHY_LAST_BLOCK;
      }
