Subject [jira] Created: (HARMONY-50) java.io.RandomAccessFile should accept all modes that are defined in the specification, including "rws" and "rwd"
Date Fri, 27 Jan 2006 06:21:33 GMT
java.io.RandomAccessFile should accept all modes that are defined in the specification, including
"rws" and "rwd"
-----------------------------------------------------------------------------------------------------------------

         Key: HARMONY-50
         URL: http://issues.apache.org/jira/browse/HARMONY-50
     Project: Harmony
        Type: Bug
    Reporter: Vladimir Ivanov
    Priority: Minor


java.io.RandomAccessFile should accept all modes that are defined in the specification, including
"rws" and "rwd"

Code to reproduce:
import java.io.*; 
  
public class test29 { 

    public static void main(String args[]) { 
	try { 
          File f = File.createTempFile("xxx", "yyy"); 
          f.deleteOnExit(); 
          
          new RandomAccessFile(f, "rws"); 
          System.out.println("PASSED 1"); 
        } catch(Throwable e) { 
          System.out.println("FAILED 1: " + e); 
        } 
	try { 
          File f = File.createTempFile("xxx", "yyy"); 
          f.deleteOnExit(); 
          
          new RandomAccessFile(f, "rwd"); 
          System.out.println("PASSED 2"); 
        } catch(Throwable e) { 
          System.out.println("FAILED 2: " + e); 
        } 
    } 
}

Steps to Reproduce: 
1. Build Harmony (check-out on 2006-01-25) j2se subset as described in README.txt. 
2. Compile test29.java using BEA 1.4 javac 
> javac -d . test29.java 
3. Run java using compatible VM (J9) 
> java -showversion test29


Output:
C:\tmp\tmp17>C:\jrockit-j2sdk1.4.2_04\bin\java.exe -showversion test29
java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
BEA WebLogic JRockit(TM) 1.4.2_04 JVM  (build ari-31788-20040616-1132-win-ia32,
Native Threads, GC strategy: parallel)

PASSED 1
PASSED 2

C:\tmp\tmp17>C:\harmony\trunk\deploy\jre\bin\java -showversion test29
java version 1.4.2 (subset)

junit test:

import junit.framework.*; 
  
public class RandomAccessFileTest extends TestCase { 
    public void testRandomAccessFile_Mode_RWS() { 
	try { 
            File f = File.createTempFile("xxx", "yyy"); 
            f.deleteOnExit(); 
          
            new RandomAccessFile(f, "rws"); 
        } catch(Exception e) { 
            fail("Unexpected exception: " + e); 
        } 
    } 

    public void testRandomAccessFile_Mode_RWD() { 
	try { 
            File f = File.createTempFile("xxx", "yyy"); 
            f.deleteOnExit(); 
          
            new RandomAccessFile(f, "rwd"); 
        } catch(Exception e) { 
            fail("Unexpected exception: " + e); 
        } 
    } 

   public static void main(String[] args) { 
        junit.textui.TestRunner.run(RandomAccessFileTest.class); 
   } 
}
