Allow whitelist to be loaded from fat jar files - #1465

Conversation
When a `META-INF/deserializable.types` file is located in a jar file nested inside another jar file (for example, a Spring Boot fat jar), it can be found as a resource but can't be read with `Files.readAllLines`. This commit changes the file reading to use an input stream that allows the file to be read in this scenario. Signed-off-by: Scott Frederick <scottyfred@gmail.com>

The commit 0c5d5f3 added support for a
META-INF/deserializable.typesfile that is read to determine the set of types that can be loaded byJsonMessageConverter. The file is read as a resource from the classpath.When the file is in a jar file that is nested within another jar file (for example, a Spring Boot fat jar), the
Files.readAllLines(Path.of(uri))used to read the file as a resource will fail, preventing the message conversion.This PR changes the file reading to use the streams API instead of the
FileAPI, which works when the file is in a flat jar or in a nested jar.
