FULL PRODUCT VERSION :
java version " 1.7.0_06 "
Java(TM) SE Runtime Environment (build 1.7.0_06-b24)
Java HotSpot(TM) Client VM (build 23.2-b09, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
The issue is that when CachedRowSetImpl.acceptChanges() is called, incorrect number of conflicts, if any, is reported. The number of conflicts is the actual number of existing rows in database, which is the size of variable 'status' defined in CachedRowSetWriter.writeData(), . It's not the conflict number that is supposed to be.

REGRESSION. Last worked in version 7

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Take PostgreSQL for example, (it can happen for any SQL database)

Create a table with following cmd
CREATE TABLE ressystem.roomdescription
(
  roomdescription_id serial NOT NULL,
  roomdescription character varying NOT NULL,
  CONSTRAINT roomdescription_pkey PRIMARY KEY (roomdescription_id)
)

Insert 3 rows as
1, " Test 1 "
2, " Test 2 "
3, " Test 3 "

Execute following jdbc calls
String query = " select roomdescription_id, roomdescription from ressystem.roomdescription " ;
Object[] values = {2, " Test2 " };
rs.setCommand(query);
rs.execute(conn);
rs.moveToInsertRow();
for(int i=0; i<values.length; i++) {
rs.updateObject(i+1,values[i]);
}
rs.insertRow();
rs.moveToCurrentRow();
rs.acceptChanges(conn);
