java.util.zip.Inflater.needsDictionary() throws unspecified IllegalStateException ---------------------------------------------------------------------------------
Key: HARMONY-86 URL: http://issues.apache.org/jira/browse/HARMONY-86 Project: Harmony Type: Bug Components: Classlib Reporter: Svetlana Samoilenko According to the j2se 1.4 and 1.5 specification java.util.zip.needsDictionary() method must not throw any exception. Harmony throws unspecified IllegalStateException that contradicts specification. Code to reproduce: import java.util.zip.*; public class test2 { public static void main(String args[]) { Inflater inf = new Inflater(); System.out.println("Inflater.needsDictionary() = "+inf.needsDictionary()); } } Steps to Reproduce: 1. Build Harmony (check-out on 2006-01-30) j2se subset as described in README.txt. 2. Compile test2.java using BEA 1.4 javac > javac -d . test2.java 3. Run java using compatible VM (J9) > java -showversion test2 Output: C:\tmp>C:\jrockit-j2sdk1.4.2_04\bin\java.exe -showversion test2 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) Inflater.needsDictionary() = true C:\tmp>C:\harmony\trunk\deploy\jre\bin\java -showversion test2 (c) Copyright 1991, 2005 The Apache Software Foundation or its licensors, as applicable. java.lang.IllegalStateException at java.util.zip.Inflater.needsDictionary(Inflater.java:212) at test2.main(test2.java:8) Siggested fix: to remove the lines in needsDictionary() method in archive/src/main/java/java/util/zip/Inflater.java : 211 if (inputBuffer == null) 212 throw new IllegalStateException(); Suggested junit test case: ------------------------ InflaterTest.java ------------------------------------------------- import java.util.zip.*; import junit.framework.*; public class InflaterTest extends TestCase { public static void main(String[] args) { junit.textui.TestRunner.run(InflaterTest .class); } public void test_needsDictionary () { Inflater inf = new Inflater(); assertFalse(inf.needsDictionary()); } } -- 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
