ConfigurationAdmin and properties starting with .
Hi guys,
I have a question: Is there any restriction on the key of a service
property, restriction that says that the key should not start with . (dot)?
I'm asking this because I'm using the configuration admin and the
configuration admin is complaining about properties that start with . when
restoring the persisted state.
java.io.IOException: Name (.alias_factory_pid) must not start or end with a
dot

Thanx Felix,
That's the kind of info I was looking for. I do have a use case related to
this but is not an hard issue, so it is not required to change the .
restriction. I just could not find why this restriction was there. Thanx for
the information.

Hi Alin,
The spec of the Configuration Admin Service (section 104.4.2
Configuration Properties) says, that property names should obey the
syntax production "symbolic-name". This is a dot-separated token list,
where the dot must not be at the start or end and each token only
consists of characters in [0..9a..zA..Z_-].
Well, the keyword here is probably "should". The Felix implementation
currently forces this when reading property names and assumes correct
names. This may arguably be debatted.
If you have a requirement for using names with leading dots or with
names using other characters, feel free to report a JIRA issue. I will
the (try to) fix this issue.
Regards
Felix
