>Description:
	Sun's `new java.io.File("").getCanonicalFile()' returns a File for the
current directory.  libgcj currently throws an IOException.
>How-To-Repeat:
Try the following...

public class foo
{
	public static void main (String args[])
	{
		try {
			System.out.println (new java.io.File("").getCanonicalFile ());
		} catch (Exception e) {
			System.err.println (e);
		}
	}
}
>Fix:

This idiom is actually used in some free software.  The work-around on
posixy systems is to change "" to ".".
