>Description:
The following code throws a FileNotFoundException even if the file is valid.

File file = new File(args[0]);
URL url;
if (file.exists()) {
     url = file.toURL();
}else{
     url = new URL(args[0]);
}
String fileName = url.getFile();
FileInputStream f = new FileInputStream(fileName);

File.toUrl() returns something like:
"file:/c:/thisiscool-gcc/examples/reflect/src/list" (java.io.File#779)
which is parsed at java.net.URL#331 after that the URL.getFile will return "/c:/thisiscool-gcc/examples/reflect/src/list". From this point all the problems begin.
- the exception is thrown probably in the native FileDescriptor: natFileDescriptorWin32.cc#116 implementations

The problem is probably in the FileInputStream implementation
>How-To-Repeat:
Compile the code using gcj --Main=main -o test.exe Main.java and run ./test.exe
>Fix:

The problem is probably in the FileInputStream implementation since the URL.toFile returns what it is expected.
