Description

If DERBY_HOME is set to an invalid location (for example a directory that does not contain lib\derby.jar), most .bat scripts in the bin directory (the ones that call derby_common.bat) report three distinct error messages, of which only one is of value to the user.

Reproduction:

C:\Derby_10\db-derby-10.2.2.0-bin>set DERBY_HOME=c:\temp

C:\Derby_10\db-derby-10.2.2.0-bin>echo %DERBY_HOME%
c:\temp

C:\Derby_10\db-derby-10.2.2.0-bin>bin\sysinfo
DERBY_HOME is set incorrectly or derby.jar could not be located. Please set DERBY_HOME.
The system cannot find the batch label specified - end
'""' is not recognized as an internal or external command,
operable program or batch file.

The distinct error messages are:

1) DERBY_HOME is set incorrectly or derby.jar could not be located. Please set DERBY_HOME.

2) The system cannot find the batch label specified - end

3) '""' is not recognized as an internal or external command, operable program or batch file.

Only 1) is relevant for the user, and should ideally be the only one displayed.
