problem with file io in kawa-1.9.1

[john whittaker <john dot whittaker at sbcglobal dot net>]

Hello Kawa users,

I have run into an issue with file io operations in Kawa.  It appears that the 
path strings I'm passing to various file io functions are creating an 
instance of the gnu.text.FilePath type and passing a value of that type to 
Java functions which are expecting java.io.File types.  Am I passing the 
wrong kind of arguments?  I've pasted a sample interaction below.

#|kawa:2|# (create-directory "/home/john/mytest")
Argument #1 (/home/john/mytest) to 'java.io.File.mkdir()' has wrong type 
(gnu.text.FilePath) (gnu.text.FilePath cannot be cast to java.io.File)
