Client socket connection doesn't report real socket exception
-------------------------------------------------------------
Key: DERBY-635
URL: http://issues.apache.org/jira/browse/DERBY-635
Project: Derby
Type: Improvement
Components: Network Client
Versions: 10.1.1.0
Reporter: John C. Landers
Priority: Minor
When opening a connection with a network url: jdbc:derby://localhost:4000/data
The netagent catchs the PrivilegedActionException but doesn't report the
checked exception in it.
Changing these lines
try {
socket_ = (java.net.Socket)
java.security.AccessController.doPrivileged(new OpenSocketAction(server, port));
} catch (java.security.PrivilegedActionException e) {
throw new DisconnectException(this,
e.getClass().getName() + " : Error opening socket to server
" + server + " on port " + port + " with message : " + e.getMessage());
}
To This returns the check exception information:
try {
socket_ = (java.net.Socket)
java.security.AccessController.doPrivileged(new OpenSocketAction(server, port));
} catch (java.security.PrivilegedActionException e) {
throw new DisconnectException(this,
e.getException().getClass().getName() + " : Error opening
socket to server " + server + " on port " + port + " with message : " +
e.getException().getMessage());
}
It currently reports messages like this:
Caused by: java.sql.SQLException: org.apache.derby.client.am.SqlException:
java.security.PrivilegedActionException : Error opening socket to server
localhost on port 1527 with message : null
With this fix it reports:
org.apache.derby.client.am.DisconnectException: java.net.ConnectException :
Error opening socket to server localhost on port 1527 with message : Connection
refused: connect
