Would it be okay if I made it clear that those two words are not English adjectives but are special symbols that happen to use Latin script and originate from the English words they resemble? If so, I could enclose each of them in `{@code ... }`. If not, I could drop that particular change from this PR.

Line 281 is (was!) consistent with line 277 because it is distinguishing 
a synchronized "static method" from a synchronized "instance method". 
There was no need to make any change to line 281 because of the 
blessed-order of modifiers as defined for method declarations! This text 
is just prose. Now for consistency you should change line 277 to refer 
to a "non-static synchronized method" (as "instance synchronized method" 
would be truly awful).

Line 49 places "static synchronized" in code font, implying that it is 
referring to the actual method modifiers and as such using the blessed 
order is appropriate. Line 49 does not need to be "consistent" with line 
281. If line 49 used a normal font so the words "static" and 
"synchronized" were just prose then either order would be perfectly fine 
in terms of English language, but then you could make a case for having 
it be consistent with line 281.

Cheers,
David
