Info properties incompatible as manifest replacement

[mattnelson]

I am trying to use the info properties as a drop in replacement for the Manifest. Unfortunately the *.properties file is changed to use = instead of : for the separator and does not append a new line at the end of file. What was the intended use case for this file? Was it for commons-config/archaius.

java.io.IOException: invalid header field
