Paulex Yang commented on HARMONY-70: ------------------------------------ This issue is similiar with issue 40(http://issues.apache.org/jira/browse/HARMONY-40), pls. refer to my comments for that issue, and these issues should be fixed by patches for issue 42(http://issues.apache.org/jira/browse/HARMONY-42). > 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.
