> BaseFormatPropertySourceProvider can handle multiple formats registered. This is useful in my project because we actually support multiple formats for a certain type of config file and this way we can implement one Provider which can provide PropertySources for all of them.
> But {{getPropertySources()}} will
> # blindly try all files with all formats. E.g. if both, "properties" and "ini" formats are registered, it will try all files with both formats without checking {{format.accepts()}} first.
> # try all the formats with the same {{InputStream}}. If the previous format does not reset the input stream, it is already at the end of the file and the following formats don't have anything left to read, returning {{null}}. This leads to some {{NullPointerException}}s being logged.
