Subject Re: building a fileset with specific permissions?

Unfortunately, exactly how the command is executed is based on both the
platform and the current JDK revision.

If you're on JDK 1.3, then it uses Runtime.exec() which quickly dives
into native code.  Under 1.1 or 1.2, it uses the antRun wrapper script
to change directories and then execute the command.  Note that on
Windows, this is the antRun.bat file.

So, my guess is that your PATH setting is causing you to find the wrong
"find" command from within the batch file.

Just a guess.

It eventually boils down to executing the antRun script
