Pretty stupid method names.
Knew a guy once (this sounds crazy, but it's a true story) who
had a hard time inventing variable names. So he wrote himself a
little program to generate random names and printed out a sheet of
a few hundred such. Thereafter, any time he needed a variable name
and was stuck for a good idea he'd just grab his printout and take
the next random name -- crossing it off so as not to re-use it and
create confusion. Result: No one could read his code, not even he.

There's absolutely nothing wrong with it; Eclipse is acting
like a nervous maiden aunt, as usual.
Somewhere in Eclipse's configuration menus there might be a way
to tell it to stop worrying about monsters under the bed. (It'll
probably be on a menu whose color scheme is dark blue on jet black.)
All I can suggest is that you search for that menu, and hope against
hope that it actually exists.
If you can't find anti-anxiety medicine for Eclipse, consider
NetBeans.
