SQL Issue with MS Access

Question

Hello;
I have an SQL query:
Select year, sum(group1) as A from table1 where name in ('test1', 'test2') group by year;
When I run it through SQL editor in MS Access it returns the years and sum and a total of 5 rows.
When I pass this command through Java: Connection.createStatement and executeQuery
I can print the values and it prints 5 rows but after printing it hangs.
When i get the size of result set :
while(rs.next())
resultSetSize ++;
System.out.println(rs.getInt(1) + "\t" +resultSetSize);
It shows the result set as size of 10, when i print the values it stops at 5. I am not sure where the issue is.
I think since my where condition is have 2 values it might be causing problem.
If I just put 1 value after my where condition, then the java code runs fine.
Can anyone tell me what the issue is here or where am I going wrong?
Thanks for your help.

Thanks for the suggestion. I checked the code. Indeed I was not printing an exception. When I printed the exception this is what i get:
Exception is: java.sql.SQLException: [Microsoft][ODBC Driver Manager] Invalid cursor state
hope this helps to guide me on how to solve this issue.
Below is the code:
public static void TestQuery()
String query="SELECT year, sum(group1) as A FROM table1 WHERE name in ('test1', 'test2') ";
Connection conn = ConnectDB1.getDBConnection(); //this gets the database parameters from a properties file
Statement stat = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
ResultSet rs = stat.executeQuery(query);
int resultSetSize=0;
while(rs.next())
resultSetSize ++;
System.out.println(rs.getInt(1) + "\t" +resultSetSize);
rs.beforeFirst();
System.out.println("Size of result set: " +resultSetSize);
while(rs.next())
System.out.println(rs.getInt(1) + "\t" + rs.getInt(2) );
rs.close();
stat.close();
conn.close();
System.out.println("End of program");
catch (Exception e){System.out.println("Exception is: " +e);}
}
