Child instances on Windows

[Castor <yg...@gmail.com>]

Enviroment: Windows 8.1 , Karaf 4.0.9 ( Also tested with 4.0.8 and 4.1.1 ) ,
JDK8 131 64bits. 

Hello! I'm encountering some problems with Karaf instances under Windows,
which does not occurs on Linux. 

1) When i run a instance:list , it shows the root instance as Stopped, the
karaf.pid file has the correct process id so does the instance.properties,
but the instance.properties after i run a instance:list sets the item.0.pid
to 0. 

2 ) When i create or clone an instance, the files are cloned/created without
any problem, but when i run a instance:start i have the following exception:

Which has it's origin at the ScriptUtils.execute() with the following props:

and runs the builder with: 

[cscript, /NOLOGO, //E:vbs,
C:\Users\ygor.santana\Downloads\apache-karaf-4.0.9\data\tmp\jpm.8845663376941377652.script]
parameters. 

The same problem occurs when i run via the instance.bat command, i've also
tested under Linux ( 
 CentOS7 and Debian ), where the behavior is ok and it's working as
intended, so it's a problem with windows only. 

It looks like a bug to me, should i open a JIRA request?

Re: Child instances on Windows

[Castor <yg...@gmail.com>]

I found the problem, it's not a karaf problem, for some bizarre reason, my
Windows does not have the vbs mechanism for cscript, i think it would be
nice to redirect the cscript output to the exception, so it would be easier
to identify problems like that.
