Subject Re: [jira] Resolved: (DERBY-721) State of InputStream retrieved from resultset is not clean , if there exists previous InputStream .
Date Mon, 19 Dec 2005 12:08:27 GMT
Hello.


I found next error of jdbcapi/Stream.java in regression test using DB2 
universal driver .
http://www.multinet.no/~solberg/public/Apache/TinderBox_Derby/testlog/SunOS-5.10_i86pc-i386/357435-derbynetmats_diff.txt

I could not found this problem , because test for DB2 universal driver 
was not executed at my environment in derbyall suite ....


The error tells that modification done in DERBY-721 made different behavior
between using  DB2 universal driver and using Network client JDBC driver .

Because this difference is a natural consequence from decision in 
DERBY-721 ,
I will add master .out file of jdbcapi/Stream.java for DB2 universal 
driver to be passed .


Best regards.
