<subsection name="Coyote">
Reviewing the code of ServiceBindingPropertySource,
1. It removes only the last end-of-line sequence (one or two characters).
It could be rewritten with a loop to remove any \n \r characters that
are found at the end.
This was intentional (only trim the final newline) but could be updated
if the team thinks it makes sense to do so.
Maybe text-editing programs append a trailing newline at the end of text
files unless you take special steps to prevent it from happening. It's
usually easy to limit the trailing newlines to a single one.
2. The code later uses "return new String(bytes, 0, length);"
to create a String, without specifying any encoding.
This was intentional as well, as the file is originally read without
specifying the encoding. Allowing an admin to specify the encoding would
have expanded the configuration for ServiceBrindingPropertySource and my
intent at the time was to make the fewest number of changes possible.
I guess that the Platform default encoding nowadays is UTF-8.
Or maybe it makes sense to use the default encoding, as people edit
those files, using whatever default encoding they prefer.
+1
A PropertySource is specified using a system property. Specifying the
encoding for a file-based PropertySource would mean having another
system property or a more complicated configuration scheme for
PropertySource.
I'm happy to entertain ideas for improvement.
