Knut Anders Hatlen updated DERBY-1710:
--------------------------------------
Attachment: derby-1710.diff
derby-1710.stat
The attached patch makes NetworkServerControlImpl use
SQLException.getSQLState() instead of EmbedSQLException.getMessageId() where
possible. Where it is not possible, check that the exception is
EmbedSQLException before casting, and fall back to a more generic approach if
it is not.
> Unchecked casts from SQLException to EmbedSQLException cause
> ClassCastException in NetworkServerControlImpl when running Java SE 6

> Since Derby doesn't raise EmbedSQLExceptions when running Java SE 6 or later,
> casts from SQLException to EmbedSQLException fail with a ClassCastException.
> To reproduce, start a network server with Java SE 6, and with
> derby.drda.debug enabled:
> java -Dderby.drda.debug=true org.apache.derby.drda.NetworkServerControl
> start
> In another terminal, stop the server with this command:
> java org.apache.derby.drda.NetworkServerControl shutdown
> When the server stops, it will print
> java.sql.SQLException cannot be cast to
> org.apache.derby.impl.jdbc.EmbedSQLException
> java.lang.ClassCastException: java.sql.SQLException cannot be cast to
> org.apache.derby.impl.jdbc.EmbedSQLException
