the standard notation for a static final...

The lower case names were in the original version of Java before they
standardized on upper case names for the static finals. The upper case
names were added in version 1.4. Use the upper case names for any new code.

It is historical. Originally they were all lower case. Then someone
pointed out this violated the static final all upper case naming
convention, and Sun fixed it. They had to leave the lower case names
to avoid breaking existing code.
