--------------------------------
Re-opening to merge fix to 10.1
> Specification of incomplete server properties on command line causes NPE with NetworkServerControl when starting the server.
> ----------------------------------------------------------------------------------------------------------------------------
>
> Key: DERBY-375
> URL: http://issues.apache.org/jira/browse/DERBY-375
> Project: Derby
> Type: Bug
> Components: Network Server
> Versions: 10.2.0.0, 10.1.1.0
> Environment: Running Derby Network Server and using command line API to start the server.
> Reporter: A B
> Assignee: Deepa Remesh
> Fix For: 10.2.0.0
> Attachments: derby-375.diff, derby-375.status, derbyall_report.txt

> When using the command line to start the Network Server, there a couple of cases where if a property is specified on the command line but no value is given (ex. "-Dderby.drda.maxThreads" instead of "-Dderby.drda.maxThreads=3"), a Null Pointer Exception will result, when the correct behavior should be to use some kind of default.
> For example:
> > java -Dderby.drda.maxThreads org.apache.derby.drda.NetworkServerControl start -p 1528
> java.lang.NullPointerException
> at org.apache.derby.impl.drda.NetworkServerControlImpl.localizeMessage(NetworkServerControlImpl.java)
> at org.apache.derby.impl.drda.NetworkServerControlImpl.consolePropertyMessageWork(NetworkServerControlImpl.java)
> at org.apache.derby.impl.drda.NetworkServerControlImpl.consolePropertyMessage(NetworkServerControlImpl.java)
> at org.apache.derby.impl.drda.NetworkServerControlImpl.getIntPropVal(NetworkServerControlImpl.java)
> at org.apache.derby.impl.drda.NetworkServerControlImpl.getPropertyInfo(NetworkServerControlImpl.java)
> at org.apache.derby.impl.drda.NetworkServerControlImpl.<init>(NetworkServerControlImpl.java)
> at org.apache.derby.drda.NetworkServerControl.main(NetworkServerControl.java)
> Note that even though we see this NPE, it appears that the server still starts up, although the startup may not be complete (subsequent attempts to connect might lead to errors like "Invalid reply from network server: Insufficient data.").
> For other properties, this will just result in the default value being used, which is the correct behavior. For example:
> > java -Dderby.drda.host org.apache.derby.drda.NetworkServerControl start -p 1528
> Server is ready to accept connections on port 1528.
