java.net.URLConnection.setUseCaches throws unspecified IllegalAccessError
--------------------------------------------------------------------------
Key: HARMONY-71
URL: http://issues.apache.org/jira/browse/HARMONY-71
Project: Harmony
Type: Bug
Components: Classlib
Reporter: Svetlana Samoilenko
According to j2se 1.4.2 specification method
java.net.URLConnection.setUseCaches(boolean) throws IllegalStateException, if
already connected. Harmony throws java.lang.IllegalAccessError instead, that
contradicts the specification.
Code to reproduce:
import java.io.IOException;
import java.net.*;
public class test2 {
public static void main(String[] args) {
HttpURLConnection u=null;
try {
u=(HttpURLConnection)(new URL("http://intel.com";).openConnection());
u.connect();
} catch (MalformedURLException e) {
System.out.println("unexpected MalformedURLException"+e);
} catch (IOException f) {
System.out.println("unexpected IOException"+f);
}
try {
u.setUseCaches(true);
} catch (IllegalStateException e) {
System.out.println("OK. Expected IllegalStateException");
e.printStackTrace();
};
}
}
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)
OK. Expected IllegalStateException
java.lang.IllegalStateException: Already connected

Suggested junit test case:
------------------------ URLConnectionTest.java
-------------------------------------------------
import java.io.IOException;
import java.net.*;
import junit.framework.*;
public class URLConnectionTest extends TestCase {
public static void main(String[] args) {
junit.textui.TestRunner.run(URLConnectionTest.class);
}
public void test_setUseCaches () {
HttpURLConnection u=null;
try {
u=(HttpURLConnection)(new URL("http://intel.com";).openConnection());
u.connect();
} catch (MalformedURLException e) {
fail("unexpected MalformedURLException"+e);
} catch (IOException f) {
fail("unexpected IOException"+f);
}
try {
u.setUseCaches(true);
} catch (IllegalStateException e) { //expected
};
}
}
