So I am trying to do a very simple read of a pdf file. As simple as this:
public String getSource(String pdfLink) throws IOException {
log.debug("Getting the sources for pdfLink = {}", pdfLink);
URL url = new URL(pdfLink);
URLConnection connection = url.openConnection();
//60 seconds connection timeout
connection.setConnectTimeout(1000 * 60);
PdfReader reader = new
PdfReader(this.getResponseAsBytes(connection.getInputStream()));
int numberOfPages = reader.getNumberOfPages();
StringBuilder builder = new StringBuilder();
for(int i=1;i<=numberOfPages;++i){
String result = PdfTextExtractor.getTextFromPage(reader, i);
System.out.println("AAAAAAAAAA = "+result);
builder.append(result);
}
return builder.toString();
}
/**
* read chunks of 1024 bytes from input stream and put them into
the output stream
*/
private byte[] getResponseAsBytes(InputStream inputStream) throws
IOException{
byte[] bytes = new byte[1024];
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
while(inputStream.read(bytes)!=-1) outputStream.write(bytes);
return outputStream.toByteArray();
}
as a result I get:
Exception in thread "main" java.lang.NullPointerException

Funny thing, If I downgrade to 2.1.7 everything works fine.
This very much sounds like a bug to me.
Cheers,
Eugene.
