NetworkClient closes resultset when next() moves the cursor beyond the last row

URL: http://issues.apache.org/jira/browse/DERBY-403
Project: Derby
Type: Bug
Components: Network Client
Reporter: Bernt M. Johnsen
NetworkClient closes resultset when next() moves the cursor beyond the last row
The following stub will work in EmbeddedDriver but not in NetworkClient:
while (rs.next()) {
}
rs.getMetaData();
In NetworkCLient, you get:
Exception in thread "main" org.apache.derby.client.am.SqlException: Invalid
operation: result set closed
at
org.apache.derby.client.am.ResultSet.checkForClosedResultSet(ResultSet.java:3269)
at
org.apache.derby.client.am.ResultSet.getMetaDataX(ResultSet.java:1386)
at org.apache.derby.client.am.ResultSet.getMetaData(ResultSet.java:1377)
This causes problems for Derby NetwokClient when used with SQuirreL
