setOption() and setExtendedOption() of JavacTool will throw exception for some defined options.

Please see the testcase :
<code>
import java.io.*;
import javax.tools.*;

public class Test10 {
    public static void test (String... args) {
        JavacTool javac = com.sun.tools.javac.Tool.create();
        javac.setOption("-target","1.5");
        DiagnosticListener dl = new DiagnosticListener() {
                public void problemFound (DiagnosticMessage message) {
                    System.out.println (
                            new File(message.getSourceName().toString()).getName()
                            +":"+message.getStartPosition()+":"
                            +message.getStartPosition()+":"+message.getPosition());
                    System.out.println(message.toString());
                    System.out.format("Found problem: %s%n", message.getKey());
                    System.out.flush();
                }
        };
        PrintWriter writer = null;
        javac.run ( (InputLocator) null, null, dl, writer, args);
    }
    public static void main (String... arg) {
        Test10 test = new Test10();
        test.test("/home/sa151881/javatrails/SWarnings/unchecked/Test26.java");
    }
}

The same output will come for the following options
       javac.setOption("-d","/home/sa151881/javatrails/SWarnings/unchecked/");
       javac.setOption("-verbose");
// First it give the output but at the end it gives the same output
       javac.setOption("-cp","/home/sa151881/javatrails/SWarnings/unchecked");
       javac.setOption("-classpath","/home/sa151881/javatrails/SWarnings/unchecked");
       javac.setOption("-encoding","UTF-8");
       javac.setOption("-target","1.5");
       javac.setOption("-sourcepath",".");
       javac.setOption("-Xstdout","out.txt");
       //Creates the out put file the same exception
       javac.setOption("-endorseddirs", "/home");
       javac.setOption("-source", "1.5");
       javac.setOption("-help");
       //First displays the help and then the same output
       javac.setOption("-X");
       //First displays -X options and then the same output

setOption will throw NullPointerException when the following options are used
javac.setOption("-bootclasspath","");
        javac.setOption("extdirs",";");
        javac.setOption("-J-Xms48m");
