You need to check if there is more to read from InputStream.

String hexString =  StringUtils.deleteWhitespace("03 67 01 10 05 67 00 FF");
byte[] bytes = Hex.decodeHex(hexString.toCharArray());
org.himalay.lpp.LPPDataFactory.LPPData data = null;
while (dis.available() > 0){
data = LPPDataFactory.createMsg(dis, new IntegerHolder());
data.dump();
}
