Subject Config admin doesn't correctly store strings containing backslashes
Date Fri, 29 Sep 2017 08:06:47 GMT
Really? I find this somewhat hard to believe, but I'm fairly sure this is the case.

Anyway. I'm using config admin to update a configuration from within a karaf command. One
of the properties is a string that contains a filename. I'm on Windows. Filename therefore
contains backslashes.
I type in 
    c:\work\tomq.keytab

I have double checked with the debugger that what my Hashtable contains is a string with backslashes
in, it's not that the backslashes are being removed by the shell command input reader. 

I call "update" on the configuration. My component correctly sees the filename with backslashes.
The properties file gets written with something like:

  file = "c:\\work\\tomq.keytab"

So so far so good. However, it I restart karaf, it seems to go wrong. 
So with karaf stopped, the file still contains the same value.
I start karaf. My component is then activated with a string that has the backslashes reinterpreted
as escapes. The component sees:
    c:work      omq.keytab
The properties file is also rewritten by something so that the backslashes have been reinterpreted
in, well a way I don't understand. It now contains:
file =  "c:work\tomq.keytab"

I don't know who is responsible here, whether this is all felix fileinstall, or karaf. 
I'm using karf 4.1.2.
If it makes a difference, my component is written using declarative services and has something
along the lines of:

    @interface Config { String file{}; }
    @Activate putlic void activate(Config config) {}

I've double checked this a few times as I feel I must be seeing things, because surely this
should work?
Can anyone confirm my madness/sanity?

Thanks.
