This happens because of an unexpected colon ":" in the file name, which is
wrongfully matched by the ConfigTransformer.DEFAULT_PATTERN in these three
groups "file", "/F" and "/properties.txt:fileKey" instead of "file",
"/F:/properties.txt" and "fileKey".
The ConfigTransformer.DEFAULT_PATTERN should be changed to match the first and
the last colon ":" in the expression.
