Hi Tom, I can confirm your problem. Lists are not recognized as typed properties. The regular expression that is used in org.apache.felix.utils.properties.Properties.PropertiesReader is incomplete and cannot handle list types.
I have opened the following Jira issue: https://issues.apache.org/jira/browse/FELIX-6042 I have fixed the issue and created a pull request, which can be found here: https://github.com/apache/felix/pull/176 The pull request contains two small tests to make sure, that the issue does not reappear in future. I had to made some changes to the existing tests, because they failed on Windows platforms. Thank you very much for your detailled problem analysis, that made it much easier to find a solution.

Or at least, it's behaving unexpectedly. Arrays are fine, it only applies to lists. When writing a List out, it uses (). However in org.apache.felix.utils.properties.Properties.PropertiesReader there is logic to detect whether the value is "typed" or not. The regular expression *doesn't* allow for a value surrounded by (). So when reading the same file back in it doesn't think it's typed, so doesn't convert any of the values and leaves them all as strings. The effect is that if you save properties, and one of them is a list, on reading them back in, they are all returned as strings, complete with quotation marks, type characters etc. This seems like a bug to me? I'm not very good with regex, but a simple modification to the regex in PropertiesReader.nextProperty would seem to solve it?
