Why does recompile even source not modified?

In my attempt to understand javac, I have set a task to compile a few java
files
in a package util.* (project name is 'stp')

<target name='utils'>
  <javac srcdir="/stp/utils" destdir='/stp'
      includes='*.java' verbose='yes'
      excludes='Copy.java'
  />
</target>
The first compile went OK. The subsequent times I ran ant again, it does
recompile
all the class files.
Note that each java file has the declaration 'package utils;' in them.

Sample output for one file
    [javac] [checking utils.MediatedThreadIf]
    [javac] [wrote C:\stp\utils\MediatedThreadIf.class]

What did I do wrong
Thanks in advance

Man, you're good. Fixed my build file and it worked.
What do I owe you so far?

Use:
<target name="utils">
  <javac srcdir="/stp" destdir="/stp"
       includes="util/*.java" 
       excludes="util/Copy.java"
       verbose="yes/>
</target>

IOW: The "srcdir" attr should point up to where the package hierarchy
begins, and the filenames should begin with the package hierarchy -- it's
how it matches source-files to class-files.
