java.io.FilePermissions should pay attention to system file separator
---------------------------------------------------------------------
Key: ADDR-12
URL: http://issues.apache.org/jira/browse/ADDR-12
Project: Addressing
Type: Bug
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)
