Subject [jira] Commented: (HARMONY-4135) [classlib][luni] InputStream handles UTF-16 incorrectly
Date Fri, 15 Jun 2007 15:23:26 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-4135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12505267
] 

Mikhail Markov commented on HARMONY-4135:
-----------------------------------------

Generally this was not the problem in io, but in String.getBytes() method which called decode()
method of CharsetDecoder.
Here is the simplified test:
public final class Test {
    public static void main(String[] args) throws Exception {
        byte[] buf = "-".getBytes("UTF-16");
        System.out.println("buf[0] = " + (buf[0] & 0xFF) + ", buf[1] = " + (buf[1] &
0xFF));
    }
}
So, i think the regression test should be added to String2Test which tests this method. I'll
provide the patch for this test soon.

>         int second = (input.read() & 0xFF);
>         System.out.println("" + first + " " + second);
>     }
> }
