we have oracle 9i database and jdeveloper 10g installed on our machine. we tried to connect our database in jdeveloper by using new database connection wizard. at the end of the connection wizard, tool says that the connection is successful(by issuing the message "Success!"). At the end we get the following exception: java.lang.NullPointerException
	at oracle.jdevimpl.cm.dt.ConnectionController$ConnectionExpander.selectConnection(ConnectionController.java:547)
