According to java code conventions
Comment From: sbrannen
For the record, the proposed changes are to SpEL "property names", not variable names.
As stated in the same chapter:
Case insensitivity is allowed for the first letter of property names.
Thus, person.name, person.Name, Person.Name, and person.getName() are all equivalent with regard to property access in SpEL.
It's ultimately a matter of taste. Some people prefer to follow Java conventions. Others prefer capitalized property names in expressions for improved readability.
In any case, I do think it would be beneficial to focus on Java coding conventions in the examples, with a NOTE pointing out more explicitly what I've stated above.
In light of that, I'll probably merge this PR as-is and add such a note.
