Hi. Can anyone explain to me how this works? In the close_ method of
client.net.NetAgent.java there is the following code:
accumulatedExceptions =
new SqlException(logWriter_, e, "A
communication error has been detected. " +
"Communication protocol being used: {0}. " +
"Communication API being used: {1}. " +
"Location where the error was detected: {2}. " +
"Communication function detecting the error:
{3}. " +
"Protocol specific error codes(s) {4}, {5},
{6}. " +
"TCP/IP " + "SOCKETS " + "Agent.close() " +
"InputStream.close() " + e.getMessage() + " " +
"* " + "0");
Note the massive use of placeholders, and then none of the values for
the placeholders are provided.
This is repeated three times throughout the close() method as exceptions
are accumulated.
I track through to the SqlException code and the message appears to be
simply stored verbatim and ultimately a chain of SqlExceptions are
thrown to the user, with the placeholders not filled in.
I did a little test to throw this exception unconditionally and, which
is what I would have expected, I get the following text:
> java.sql.SQLException: A communication error has been detected.
Communication
protocol being used: {0}. Communication API being used: {1}. Location
where the
error was detected: {2}. Communication function detecting the error:
{3}. Protoc
ol specific error codes(s) {4}, {5}, {6}. TCP/IP SOCKETS Agent.close()
InputStre
am.close() blahblah * 0
Am I missing some magic here? Or is this just a bug that was never
uncovered?
Thanks,
David
