Subject [jira] Created: (HARMONY-2467) java.nio.charset.CharsetDecoder(cs, Float.MIN_VALUE,Float.MIN_VALUE) does not throw IllegalArgumentException
Date Tue, 05 Dec 2006 14:16:22 GMT
java.nio.charset.CharsetDecoder(cs, Float.MIN_VALUE,Float.MIN_VALUE) does not throw IllegalArgumentException
------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2467
                 URL: http://issues.apache.org/jira/browse/HARMONY-2467
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Anton Ivanov
            Priority: Minor


According to the specification constructor must throw IllegalArgumentException if the preconditions
on the parameters do not hold.
java.nio.charset.CharsetDecoder(cs, Float.MIN_VALUE,Float.MIN_VALUE) does not throw IllegalArgumentException
while RI does with message:
   java.lang.IllegalArgumentException: Replacement too long

Test to reproduce the problem:

import junit.framework.TestCase;
import java.nio.charset.*;
import java.nio.*;

public class test10036 extends TestCase {     
    public void test1 () { 

        try {                              
            CharsetDecoderImpl obj = new CharsetDecoderImpl(Charset.forName("UTF-8"),
                    Float.MIN_VALUE , Float.MIN_VALUE );   
            fail("IllegalArgumentException should be thrown");                 
        } catch (IllegalArgumentException e) { 
            //expected
        }        
    }

}

class CharsetDecoderImpl extends CharsetDecoder{

    public CharsetDecoderImpl(Charset cs, float averageBytesPerChar,
            float maxBytesPerChar){
        super(cs, averageBytesPerChar, maxBytesPerChar);
    }

    public CoderResult decodeLoop(ByteBuffer out, CharBuffer in) {
                return CoderResult.UNDERFLOW;
    }
}
