javadoc to the getOutput(ProcessBuilder processBuilder) method of jdk.test.lib.process.ProcessTools incorrectly calls the parameter as "processHandler":

    /**
     * Pumps stdout and stderr from running the process into a String.
     *
     * @param processHandler ProcessHandler to run.
     * @return Output from process.
     * @throws IOException If an I/O error occurs.
     */
    public static OutputBuffer getOutput(ProcessBuilder processBuilder)

this may confuse readers and needs to be fixed.
