Subject [jira] Created: (HARMONY-47) java.io.FilePermissions should pay attention to system file separator
Date Thu, 26 Jan 2006 08:03:10 GMT
java.io.FilePermissions should pay attention to system file separator
---------------------------------------------------------------------

         Key: HARMONY-47
         URL: http://issues.apache.org/jira/browse/HARMONY-47
     Project: Harmony
        Type: Bug
  Components: Classlib  
    Reporter: Vladimir Ivanov


java.io.FilePermissions should pay attention to system file separator. For example, on Windows
file separator is \, not /, so /* shouldn't imply /<anything>

Code to reproduce:
import java.io.*; 
  
public class test29 { 
	public static void main(String args[]) throws Exception { 
        	System.out.println(new FilePermission("C:/*", "read").implies(new FilePermission("C:/a",
"read")) ? "FAILED" : "PASSED"); 
	} 
}

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

    public void testFile_String() { 
        assertFalse("/ work as file separator", new FilePermission("C:/*", "read").implies(new
FilePermission("C:/a", "read"))); 
    } 

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