Knut Anders Hatlen commented on DERBY-1256:
-------------------------------------------
I see a similar IOException when I run ReplicationRun_Local with
file.encoding=UTF-16 on OpenSolaris/JDK6:
java.io.IOException: Cannot run program
"/usr/jdk/instances/jdk1.6.0/jre/bin/java": error=2, No such file or directory

However, I see the same problem when I execute the following code with
file.encoding set (works fine without the property):
public class FileEncoding {
public static void main(String[] args) throws Exception {
Process p = Runtime.getRuntime().exec("/usr/bin/ls");
System.out.println("Status: " + p.waitFor());
}
}
Exception in thread "main" java.io.IOException: Cannot run program

So I don't think that it shows a problem in Derby or the tests.
> Remove usage of non-portable methods in derby code

>
> Key: DERBY-1256
> URL: https://issues.apache.org/jira/browse/DERBY-1256
> Project: Derby
> Issue Type: Bug
> Components: Network Server, SQL, Store, Test
> Reporter: Sunitha Kambhampati
>
> Remove usage of non portable methods that use native encoding as they could
> potentially lead to bugs on platforms with different encodings.
> Replace with code using fixed conversion, or alternative mechanisms.
> If the call is required its use should be commented as to why it is required.
> I went through the classes in java.io package in jdk1.4.2 and have come up
> with a list of methods, constructors in the java.io.* classes that use native
> encoding and did a java search on eclipse for the code in java/engine,
> java/testing, java/drda, java/client.
> 1)ByteArrayOutputStream.toString()
> testing - DerbyNetNewServer:
> System.out.println( bos.toString());
> server- NetworkServerCtrlInfo.getCLSSysInfo, getNetSysInfo,
> 2)DataInputStream.readLine()

> encoding.
> =============
> There are also non portable methods in String class
> new String(byte[])
> new String(byte[],int,int)
> String.getBytes(). There are jira entries already for these- DERBY-900,
> DERBY-901,DERBY-902,DERBY-903.
