Jochen Theodorou commented on GROOVY-8467:
------------------------------------------
I think I see the problem now. If we read A\r\nB\r\n, then readLine will make
first a line for A and then the expectation is to have the next line for B. The
loop up there will only consume the \r, not the \n. And this leads to an empty
line. So reading all lines will produce A, empty, B empty. Is that correct?

> Project: Groovy
> Issue Type: Bug

> i have a android aapt dump file
> i try to read the file use the code below:
>
> {code:java}
> InputStreamReader inputReader = new InputStreamReader(dumpFile)
> String line = null
> while ((line = inputReader.readLine()) != null){
> println(line)
> }
> {code}
> the dumpfile uses \r\n to start a new line, while the IOGroovyMethods
> readLineFromReaderWithoutMark method which called by readLine method is :
> {code:java}
> private static String readLineFromReaderWithoutMark(Reader input) throws
> IOException {
> int c = input.read();
> if(c == -1) {
> return null;
> } else {
> StringBuilder line;
> for(line = new StringBuilder(expectedLineLength); c != EOF && c != 10
> && c != 13; c = input.read()) {
> char ch = (char)c;
> line.append(ch);
> }
> return line.toString();
> }
> }{code}
> this casues an extra empty line read.
