I believe your problem may be in the recipe body.
Note from the messages above the the class file is rm'd twice.
The first time by cook's default action to remove targets before building,
the second by your recipe body.

The other thing is that when you put "file system" modifying commands in a
recipe body, such as rm,cp etc, you should either include set clearstat;
or make the commands execute as a single shell command such as below:

bin/moz_base/%.class: [resolve src/moz_base/%.class]
{
    function print "copying:" %.class;

    cp -p [resolve src/moz_base/%.class] [target] && chmod -f u+w [target];
}
