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) (c) Copyright 1991, 2005 The Apache Software Foundation or its licensors, as applicable. 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); } } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
