Henri,

fyi, I was wrong I show 'mixed mode' as well on a java -version but don't think theres anyway I really build that way.

If you really wanted to you could maybe verify one thing for me that might be pertinent to a bug report.
If I run this with my last build, (which for some reason still gets the 100+ compile errors on my project, appears to be missing all kinds of things).

import java.nio.file.*;
import java.nio.file.attribute.*;

public class Exists {

	public static void main(String[] args) {
		System.out.println("file " + args[0] + " exists is " + Files.exists(new java.io.File(args[0]).toPath()));
	}
	
}

Now with my build...
/usr/libexec/java_home -v 1.7 --exec javac Exists.java
/usr/libexec/java_home -v 1.7 --exec java Exists Exists.class
file Exists.class exists is true

For this it is fine anyhow.
I put your build back. I haven't tried the project compile with yours again but I believe it gets two errors, one of which shows the partial Files class. But for the Exists class here...
/usr/libexec/java_home -v 1.7 --exec javac Exists.java
Exists.java:7: cannot find symbol
		System.out.println("file " + args[0] + " exists is " + Files.exists(new java.io.File(args[0]).toPath()));
		                                                            ^
  symbol:   method exists(Path)
  location: class Files
1 error

Or just use javap, with yours....
/usr/libexec/java_home -v 1.7 --exec javap java.nio.file.Files
Compiled from "Files.java"
public final class java.nio.file.Files extends java.lang.Object {
  public static java.lang.String probeContentType(java.nio.file.FileRef) throws java.io.IOException;

}

If your results match on this I would know it's not just a 32 bit problem for the bug report but a universal one as it is.
That is for you...
The Exists class won't compile.
javap shows a stunted java.nio.file.Files class.

Actually anyone with a 64 bit universal build could confirm this.
