Key: DERBY-1604
URL: http://issues.apache.org/jira/browse/DERBY-1604
Project: Derby

Priority: Minor
I came across this by chance. While attempting to execute a statement after a
failed named connection, ij throws a NPE. Following are ij steps
that reproduces this error:
ij version 10.2
ij> connect 'jdbc:derby:grntrvkdb;create=true' user 'raj' as raj;
WARNING 01J01: Database 'grntrvkdb' not created, connection made to existing
database instead.
ij> show connections;
RAJ* - jdbc:derby:grntrvkdb
* = current connection
ij> connect 'jdbc:derby:grntrvkdb;create=true' user 'raj2' as raj2;
WARNING 01J01: Database 'grntrvkdb' not created, connection made to existing
database instead.
ij(RAJ2)> show connections;
RAJ - jdbc:derby:grntrvkdb
RAJ2* - jdbc:derby:grntrvkdb
* = current connection
ij(RAJ2)> disconnect;
ij> show connections;
RAJ - jdbc:derby:grntrvkdb
No current connection
ij> connect 'jdbc:derby:grntrvkdb;create=true' user 'raj' as raj;

ij>
I expected an error like "IJ ERROR: Unable to establish connection" since
there does not exist any connection
to execute this statement.
