Subject [jira] Updated: (DERBY-903) Remove use of String(byte[]) and String(byte[], int, int) constructors in testing leading to non-portable behaviour
Date Thu, 16 Feb 2006 20:30:10 GMT
     [ http://issues.apache.org/jira/browse/DERBY-903?page=all ]

Myrna van Lunteren updated DERBY-903:
-------------------------------------

    Attachment: DERBY-903_followup1_2006_02_16.stat
                DERBY-903_followup1_2006_02_16.diff

attaching follow up patch DERBY-903_2006_02_16.diff & .stat which modify test resultset.java
and coalesceTests.java to only print out a descriptive message if error 22005 is seen (currently
not the case in either test). Also removed no longer needed UnsupportedEncodingException from
dumpRS() in coalesceTests.

tested only these two tests (in normally running framework configuration, with jdk14 &
jdk15) and (using DERBY-683 test patch) with derbyTesting.encoding=UTF-16 with jdk15.

> 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.
