SQL Developer 1.1 close - no error msg (connect after changed TNS info)

Question

We installed a new QA database and as a result I had to change the connection credentials. After doing this on a connect, SQL Developer closed without any warning.
The following repro steps:
1.) I right click on the connection name and click on Properties
2.) In the New/Save Database Connection dialog I had the following in the Oracle>TNS>Connect Identifier box:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.111.xxx.xx)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = netqa) ) )
3.) I changed this to the following and then tested the connection (successfully) then clicked Save and Cancel to close the dialog:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.111.yyy.yyy)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = netqa) ) )
4.) On the connection name in the tree control, I right click, click on Connect, specified the user name and password and then OK
I then noticed that my SQL Developer application disappeared.
I opened it again and used the Test button which works fine but as soon as I click Connect it also closed the application.
I then had to choose the Basic option to setup the connection info which resolved the problem.
I reproduced this on another connection and got the same thing.
I must mention that I imported these connection from a file I created by exporting the connections from the previous production version.

I am having the same problem. Too bad no one else has replied. Test connnection works and sometimes I get into the application. The first few times I was able to get it to list the object types (tables, views, etc.) though nothing was listed when I tried to explode each list. This could be because the userid I am logging on with has no objects and I haven't figured out how to make it list all objects as I can in SQL Navigator or TOAD. Now it seems that anytime I try to open one of the connections, the application simply vanishes. No no warning, no messages, it just closes.
I AM trying to use an older unsupported DB version. The first few times when it actually connected to the DB I got a warning message about an unsupported version but now I get nothing. I am starting to think that this is an intentional glitch to punish companies that are still running older versions of their database (out of necessity). If you can connect to non-Oracle data bases it seems like an older Oracle version shouldn't matter.
Anyone else have any clues why the applicatioin just closes without warning?
