A B closed DERBY-374:

Fix for this has been in 10.1 and 10.2 since last October, so I'm marking it as closed.  Thanks
Deepa!

> If using the Derby Client to connect to the Derby Network Server, there are some cases
where an invalid URL will cause a protocol exception instead of throwing a proper error. 
The two cases I've found are as follow:
> 1) Use of a colon to separate attributes:
> When connecting to the server with JCC, a colon is required to demarcate the Derby attributes
from the JCC attributes. For the Derby Client, however, the colon is not a valid part of the
URL, so use of it should return an error.  However, the result is a protocol exception:
> ij> connect 'jdbc:derby://localhost:1528/sample:user=someUsr;password=somePwd';
> agentThread[DRDAConnThread_9,5,main]
> ERROR (no SQLState): A communication error has been detected. Communication protocol
being used: Reply.fill(). Communication API being used: InputStream.read(). Location where
the error was detected:
> insufficient data. Communication function detecting the error: *. Protocol specific error
codes(s) TCP/IP SOCKETS
> 2) Use of double-quotes to specify a full path to a database.
> The use of double-quotes around a database path is required when connecting to the server
with JCC, but should be optional when using the Derby Client.  However,  attempts to use the
double-quotes doesn't work--on the contrary, it throws a protocol exception:
> ij> connect 'jdbc:derby://localhost:1528/"C:/myDBs/sample"';
> agentThread[DRDAConnThread_11,5,main]
> ERROR (no SQLState): A communication error has been detected. Communication protocol
being used: Reply.fill(). Communication API being used: InputStream.read(). Location where
the error was detected:
> insufficient data. Communication function detecting the error: *. Protocol specific error
codes(s) TCP/IP SOCKETS
> Without quotes, the above example will work as expected.
> I'm not sure if the problem is with the Derby client or the Network Server (more investigation
required).
