Paul King commented on GROOVY-8467:
-----------------------------------
Workaround: use readLines() or eachLine{ ... } (but they won't give you the
same level of streaming capability) or a reader with mark supported. The
comment on that method indicates that this is a known design limitation:
{code}
/*
* This method reads without a buffer.
* It returns too many empty lines if \r\n combinations
* are used. Nothing can be done because we can't push
* back the character we have just read.
*/
private static String readLineFromReaderWithoutMark(Reader input)
{code}
> IOGroovyMethods class readLine method works unexpected in

> 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.
