I couldn't find an appropriate bug in bugzilla, but this fails
reliably for me with Java 8 and 9 on Windows 10, 64-bit:
mkdir foo
mklink /J bar foo
cd bar
java -cp Test .
where Test.java is as simple as:
import java.io.*;
import java.nio.file.*;
public class Test {
public static void main(String[] args) throws Exception {
System.out.println("p.toRealPath(): " + Paths.get(args[0]).toRealPath());
}
}
The thrown error shows:
Exception in thread "main" java.lang.InternalError: Should not get here
at sun.nio.fs.WindowsNativeDispatcher.GetFinalPathNameByHandle(Native
Method)
at sun.nio.fs.WindowsLinkSupport.getFinalPath(Unknown Source)
at sun.nio.fs.WindowsLinkSupport.getRealPath(Unknown Source)
at sun.nio.fs.WindowsPath.toRealPath(Unknown Source)
at sun.nio.fs.WindowsPath.toRealPath(Unknown Source)
Is this just me? :)
