Hi,

I am trying to read a text file from the blostore like this:
[code]
AppEngineFile file = new AppEngineFile(AppEngineFile.FileSystem.BLOBSTORE, blobKey.getKeyString());
FileReadChannel frc = fileService.openReadChannel(file, false);
BufferedReader reader = new BufferedReader(Channels.newReader(frc, "UTF8"));
String line = "";
while ((line = reader.readLine()) != null) {
  // do stuff
}
reader.close();
frc.close();
[/code]

In some cases readline() generates the exception below. Url to systematically produce the exception:
