Subject [jira] Created: (HARMONY-2404) java.io.PipedWriter.write(buf,off,len) throws exeptions in different order than RI
Date Mon, 04 Dec 2006 11:31:21 GMT
java.io.PipedWriter.write(buf,off,len) throws exeptions in different order than RI
----------------------------------------------------------------------------------

                 Key: HARMONY-2404
                 URL: http://issues.apache.org/jira/browse/HARMONY-2404
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Artem Aliev
            Priority: Minor



java.io.PipedWriter.write(buf,off,len) throws exeptions in different order than
RI. 
Harmony at first checks boundary condition while RI checks pipe connection.
Compatibility issue.

Test for reproducing:
import junit.framework.TestCase;
import java.io.*;

public class test extends TestCase {      
    public void test1 () { 
        try {            
           PipedWriter obj=new PipedWriter();
           obj.write(new char[]{1,1},10,1);
           fail("IOException should be thrown");  
        } catch (IOException e) {
            //expected
        }
    } 

}
Output on Sun 1.5:
==================
.
Time: 0

OK (1 test)

Output on Harmony:
==================
.E
Time: 0.015
There was 1 error:
1) test1(test)java.lang.IndexOutOfBoundsException
        at java.io.PipedWriter.write(PipedWriter.java:166)
        at test.test1(test.java:8)
        at java.lang.reflect.VMReflection.invokeMethod(Native Method)

FAILURES!!!
Tests run: 1,  Failures: 0,  Errors: 1

The same issue if first parameter buffer==null.
Harmony throws NullPointerException while RI at first checks pipe connection
and throws java.io.IOException: Pipe Not Connected.

import junit.framework.TestCase;
import java.io.*;

public class test extends TestCase {      

    public void test2 () { 
        try {            
           PipedWriter obj=new PipedWriter();
           obj.write((char[])null,10,1);
           fail("IOException should be thrown");  
        } catch (IOException e) {
            //expected
        }
    }     
}
