I just downloaded jaybird 2.0 to test

My spec:
Firebird 1.52 ss
Java 1.5

Everything works top-notch with jaybird 1.55, but with the new Jaybird
I get the following error message:

org.firebirdsql.jdbc.FBSQLException: The result set is closed
at
org.firebirdsql.jdbc.FBResultSet.checkCursorMove(FBResultSet.java:217)
at org.firebirdsql.jdbc.FBResultSet.next(FBResultSet.java:249)


And the error occurs at:
String query="select x,y from z order by x";
Statement st=conn.createStatement();
ResultSet rs,rs2=null;

rs=st.executeQuery(query);
while(rs.next()) --> here

conn is a normal Connection type

Am I a RTFM newbie and do I really need to change something in my code
to be able to use Jaybird 2.0 or is this some kind of punishment for
me not eating my spinach (which I actually did)?

Thanks,
Popeye
