Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Vladimir Ivanov
The Harmony method java.lang.String(byte[] bytes, int offset, int length, String charsetName) throws IllegalArgumentException while RI creates object.
==================== test.java =======================
import java.nio.charset.Charset;
public class test {
public static void main (String [] args) throws Exception {
byte [] b = new byte[256];
for (int i = 0; i < b.length; i++) {
b[i] = (byte)i;
}
System.out.println("res = " + new String(b, 170, 30, Charset.forName("UTF-8").name()));
}
}

Mark Hindess commented on HARMONY-1111:
---------------------------------------
I don't think this is the correct fix. With this fix, the following line of code:
java.nio.charset.CoderResult.malformedForLength(0)
no longer throws an IllegalArgumentException even though the RI does throw such an exception.

[jira] Commented: (HARMONY-1111) [classlib][lang] unexpected
IllegalArgumentException for String(byte[], int, int, String)
Posted by "Vladimir Ivanov (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-1111?page=comments#action_12431524 ]
Vladimir Ivanov commented on HARMONY-1111:
------------------------------------------
The root reason of this issue is different behavior RI vs Harmony to decode bytes from the range 0xC0-0xFF (according to the JVMS it is 2 and 3 bytes symbols in the UTF-8 strings).
According to the API spec for this constructor:
"The behavior of this constructor when the given bytes are not valid in the given charset is unspecified"
So, for invalid array of bytes RI returns '0x3f' while Harmony returns '0x1a' or throws exception.
Proposed patch is invalid. Seems, the String constructor should be fixed.
============ test.java =====================
import java.nio.charset.Charset;
public class test {
public static void main (String [] args) throws Exception {
byte[] b = {(byte)0xBF};
String str = new String(b, 0, 1, Charset.forName("UTF-8").name());
b = str.getBytes();
System.out.print("0x");
for (int i = 0; i < b.length; i++) {
System.out.print(Integer.toHexString(b[i]));
}
System.out.println("");
byte[] b1 = {(byte)0xC0};
str = new String(b1, 0, 1, Charset.forName("UTF-8").name());
b1 = str.getBytes();
System.out.print("0x");
for (int i = 0; i < b1.length; i++) {
System.out.print(Integer.toHexString(b1[i]));
}
}
}
