Subject [jira] Commented: (DERBY-901) Remove use of String(byte[]) constructors in network server leading to non-portable behaviour
Date Fri, 14 Apr 2006 21:06:01 GMT
    [ http://issues.apache.org/jira/browse/DERBY-901?page=comments#action_12374571 ] 

Sunitha Kambhampati commented on DERBY-901:

There is one place in DRDAConnThread.readAndSetParams  where this non portable constructor
is used.
				case  DRDAConstants.DRDA_TYPE_NFIXBYTE:
				byte[] paramVal = reader.readBytes();
				if (SanityManager.DEBUG) 
					trace("fix bytes parameter value is: "+new String(paramVal));
				ps.setBytes(i+1, paramVal);

I can see two ways of fixing this,.
1) to change the trace message to say uses native encoding and leave it at that . 
2) change String to use "UTF-8"  encoding and add code to catch the unsupported encoding exception.

Does anyone have any opinions here ?

> These constructors use the Java default platform encoding to convert the bytes to a String,
this typically leads 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.
