 * destroying the compile time wall. This way, we can keep the wall up.
 * 
 * @param srcDir
 *            Directory to copy files from/to(Usually the java files dir or
 *            the class files dir)
 * @param fileset
 *            The fileset of files to include in the move.
 * @param moveToTempFile
 *            true if moving src files to temp files, false if moving temp
 *            files back to src files.
 * @param isJavaFiles
 *            true if we are moving .java files, false if we are moving
 *            .class files.
