INDIKA KUMARA commented on DERBY-5261: -------------------------------------- I have fixed DERBY-5261 bug. When it is run with the command "java -jar derbynet.jar abc" it give same error twice. I searched what was the error. I was able to find it in java file "NetworkServerControlImpl.java" at lines 2476 and 2309.Same error message print in the method "private int findCommand(String [] args)"(line 2476) and calling place of it(line 2309). after I commented line 2476 and test it again with the command "java -jar derbynet.jar abc" then it print error message once only. I attach patch file with this. > NetworkServerControl prints usage message twice on some errors > -------------------------------------------------------------- > > Key: DERBY-5261 > URL: https://issues.apache.org/jira/browse/DERBY-5261 > Project: Derby > Issue Type: Bug > Components: Network Server > Affects Versions: 10.8.1.2 > Reporter: Knut Anders Hatlen > Assignee: INDIKA KUMARA > Priority: Minor > Labels: derby_triage10_9 > > If you invoke NetworkServerControl with an invalid command, the usage message > will be printed twice. > $ java -jar derbynet.jar abc > Mon Jun 06 10:14:25 CEST 2011 : Command abc is unknown. > Usage: NetworkServerControl <commands> > Commands: > start [-h <host>] [-p <portnumber>] [-noSecurityManager] [-ssl <sslmode>] > shutdown [-h <host>][-p <portnumber>] [-ssl <sslmode>] [-user <username>] > [-password <password>] > ping [-h <host>][-p <portnumber>] [-ssl <sslmode>] > sysinfo [-h <host>][-p <portnumber>] [-ssl <sslmode>] > runtimeinfo [-h <host>][-p <portnumber>] [-ssl <sslmode>] > logconnections {on|off} [-h <host>][-p <portnumber>] [-ssl <sslmode>] > maxthreads <max>[-h <host>][-p <portnumber>] [-ssl <sslmode>] > timeslice <milliseconds>[-h <host>][-p <portnumber>] [-ssl <sslmode>] > trace {on|off} [-s <session id>][-h <host>][-p <portnumber>] [-ssl <sslmode>] > tracedirectory <traceDirectory>[-h <host>][-p <portnumber>] [-ssl <sslmode>] > Mon Jun 06 10:14:25 CEST 2011 : No command given. > Usage: NetworkServerControl <commands> > Commands: > start [-h <host>] [-p <portnumber>] [-noSecurityManager] [-ssl <sslmode>] > shutdown [-h <host>][-p <portnumber>] [-ssl <sslmode>] [-user <username>] > [-password <password>] > ping [-h <host>][-p <portnumber>] [-ssl <sslmode>] > sysinfo [-h <host>][-p <portnumber>] [-ssl <sslmode>] > runtimeinfo [-h <host>][-p <portnumber>] [-ssl <sslmode>] > logconnections {on|off} [-h <host>][-p <portnumber>] [-ssl <sslmode>] > maxthreads <max>[-h <host>][-p <portnumber>] [-ssl <sslmode>] > timeslice <milliseconds>[-h <host>][-p <portnumber>] [-ssl <sslmode>] > trace {on|off} [-s <session id>][-h <host>][-p <portnumber>] [-ssl <sslmode>] > tracedirectory <traceDirectory>[-h <host>][-p <portnumber>] [-ssl <sslmode>] > Printing it once should be enough. > The same problem is seen if you don't specify a required argument for an > option.
