fix for the described error

Only on Windows you get always an IOException even with itweb-settings and with
all webstart-apps. The reason for that is the changeset 1516:ae243b9d535c 

Here the stacktrace (from a build of a clone of
http://icedtea.classpath.org/hg/release/icedtea-web-1.7):

The patch for PathsAndFiles.java is only cosmetically, the patch for
LockedFile.java prevent the exception.
