[INACTIVE] Avian is a lightweight virtual machine and class library designed to provide a useful subset of Java's features, suitable for building self-contained applications.
I was trying to open an File URL like "file:///c:/temp/xy.txt" on Windows, and got an IOException.
After looking into avians FileURLConnection i thought the error was here, but testing somewhat further showed that the File class is also buggy. Exactly in its normalize method.
It does not remove the "/" from the beginning, which is done by Oracle JDK when creating a File like this: new File("/c:/temp/xy.txt")
To fix both bugs i changed avian.file.Handler getInputStream() to look like this.
public InputStream getInputStream() throws IOException {
return new FileInputStream(new File(url.getFile()));
}
and java.io.File normalize(String path) to look like this:
private static String normalize(String path) {
if(path.length() > 2
&& path.charAt(0) == '/'
&& path.charAt(2) == ':')
{ //remove a leading slash on Windows
path = path.substring(1);
}
return stripSeparators
("\\".equals(FileSeparator) ? path.replace('/', '\\') : path);
}
I think this should not break any other Operating system.
Please include this fix in further releases...
Thanks for this great software...
