> In the work of DERBY-1301, I found this issue.
> Seeing the code, next part in org.apache.derbyTesting.functionTests.tests.jdbcapi.Stream.TestDataReader had problem.
> public int read( char[] cbuf,
> int off,
> int len ){
>
> if(wroteLength >= total)
> return -1;
>
> int i;
> for(i = off ;
> i < off + len &&
> wroteLength <= total ;
> i++, wroteLength ++){
>
> cbuf[i] = (char) (wroteLength % 0x10000L);
>
> }
> return i - off;
> }
> Problem exists in next part...
> wroteLength <= total
> Because an evaluation of this expression is true when wroteLength equals total,
> test data is created beyond max length passed in total.
