java.io.FileInputStream.close() must close channel associated with this
FileInputStream
---------------------------------------------------------------------------------------
Key: HARMONY-70
URL: http://issues.apache.org/jira/browse/HARMONY-70
Project: Harmony
Type: Bug
Components: Classlib
Reporter: Vladimir Ivanov
J2SE 1.4 specification reads for the method java.io.FileInputStream.close() :
"If this stream has an associated channel then the channel is closed as well."
But the channel is still opened.
Code to reproduce:
import java.io.*;
import java.nio.channels.*;
public class test29 {
public static void main(String[] args) {
try {
File f = File.createTempFile("temp", ".txt");
f.deleteOnExit();
FileInputStream fis = new FileInputStream(f);
FileChannel fch = fis.getChannel();
fis.close();
System.out.println("fch.isOpen = " + fch.isOpen());
} catch (Exception e) {
System.out.println("unex = " + e);
}
}
}
Steps to Reproduce:
1. Build Harmony (check-out on 2006-01-30) 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)
fch.isOpen = false
C:\tmp\tmp17>C:\harmony\trunk\deploy\jre\bin\java -showversion test29
java version 1.4.2 (subset)

fch.isOpen = true
junit test:
------------------------ FileInputStreamTest.java
-------------------------------------------------
import java.io.*;
import java.nio.channels.*;
import junit.framework.*;
public class FileInputStreamTest extends TestCase {
public static void main(String[] args) {
junit.textui.TestRunner.run(FileInputStreamTest.class);
}
public void testClose() {
try {
File f = File.createTempFile("temp", ".txt");
f.deleteOnExit();
FileInputStream fis = new FileInputStream(f);
FileChannel fch = fis.getChannel();
fis.close();
assertFalse("FAILED, channel still opened!", fch.isOpen());
} catch (Exception e) {
fail("Unexpected exception: " + e);
}
}
}
