$ c:\installs\cygwin\bin\patch.exe -p0<  multithread_utilities_trunk.diff
(Stripping trailing CRs from patch.)
patching file xxx/yyy/zzz/Test.java

now attempt to use the files I just patched:

$ mvn clean install
...
[ERROR] error: error reading xxx\yyy\zzz\Test.java;
xxx\yyy\zzz.java (Access is denied)

I was able to reproduce this on another computer, as well.
Windows 7, 64 bit, blah blah blah.

When I right click on the files and go to properties ->  security,
somehow all users except administrators have no rights to the modified
files.

This could be related to the problem discussed starting at


http://cygwin.com/ml/cygwin/2009-11/msg00922.html

The issue there was ACLs on the temporary directory used by patch. The resolution of that was to set TMP and TEMP to "/tmp" in Cygwin's default startup files (see /etc/defaults/profile). But you appear to be running patch outside of a Cygwin shell, so you're not benefiting from that fix. (I'm basing this guess on the fact that you start patch by giving its Windows path.)
