Hello.
I think we can ignore test which corresponds to differece of 8a9 .
I found that InputStream was not closed .
This is not correct in spec of java.sql.ResultSet .
However, the InputStream was exactly ByteArrayInputStream as shown in error
message .
> FAIL - stream was not closed after a get*() call. class
java.io.ByteArrayInputStream
And Java API spec says that closing ByteArrayInputStream has no effect .
http://java.sun.com/j2se/1.4.2/docs/api/java/io/ByteArrayInputStream.html
Closing a ByteArrayInputStream has no effect.
The methods in this class can be called after the stream has been closed
without generating an IOException.
Then the behavior of the program does not differ , wheter InputStream was
closed or not.
I think no problem here .
// There remains a suspicion that it may be bad that ByteArrayInputStream is
used there , in view of performance ....
// It is too heavy item in this issue. I leave it as suspicion found n
DERBY-596 now .
Best regards .

Subject: [jira] Commented: (DERBY-596) jdbcapi/resultsetStream.java fails in
DerbyNetClient Framework

http://issues.apache.org/jira/browse/DERBY-596?page=comments#action_12331273 ]
Tomohito Nakayama commented on DERBY-596:
-----------------------------------------
Next code is where difference of 8a9 was happended .
org.apache.derbyTesting.functionTests.tests.jdbcapi.resultsetStream: L166
InputStream is = rs.getBinaryStream(1);
<snip>
System.out.println("second columns is " + rs.getInt(2));
System.out.println("FAILS DUE TO BUG 5710");
try {
is.read();
System.out.println("FAIL - stream was not closed after a get*() call. " +
is.getClass());
break;
} catch (IOException ioe) {
// yes, stream should be closed
}
According to Note at next url , InputStream "is" must be closed implicitly when
rs.getInt(2) was evaluatted .
http://java.sun.com/j2se/1.4.2/docs/api/java/sql/ResultSet.html#getBinaryStream(int)
However InputStream "is" was not closed and "is.read()" was unsuccessfully
successed .
At last, message of "FAIL - stream was not closed after a get*() call. class
java.io.ByteArrayInputStream " was generated .
jdbcapi/resultsetStream.java fails in DerbyNetClient Framework
---------------------------------------------------------------
Key: DERBY-596
URL: http://issues.apache.org/jira/browse/DERBY-596
Project: Derby
Type: Bug
Components: Network Server, Test, Network Client
Versions: 10.2.0.0
Reporter: Tomohito Nakayama
Assignee: Tomohito Nakayama
Working in DERBY-525, I found that jdbcapi/resultsetStream.java , which was originally excluded from DerbyNetClient Framework,
fails, if added to.
Next is resultsetStream.diff :
