> Remove usage of non-portable methods in derby code
> --------------------------------------------------
>
> Key: DERBY-1256
> URL: http://issues.apache.org/jira/browse/DERBY-1256
> Project: Derby
> Issue Type: Bug
> Components: SQL, Network Server, Store, Test
> Reporter: Sunitha Kambhampati
> Fix For: 10.2.2.0
>
>
> 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()
> ArrayInputStream - org.apache.derby.iapi.services.io - java/engine
> readLine()
> CorruptRandomAccessFile - org.apache.derbyTesting.functionTests.util.corruptio - java/testing
> readLine()
> 3)InputStreamReader(InputStream)

> 4) OuputStreamWriter(OutputStream)

> readLine()
> DerbyNetAutoStart - org.apache.derbyTesting.functionTests.tests.derbynet - java/testing -
> checkLog(RandomAccessFile, String[])
> PrintStream and PrintWriter , print methods uses platforms default charset 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.
