Hmm, I admit I didn't look in detail at your problem to ensure that it
could be solved by 'cinoptions', that was just my first (and probably
the easiest) solution that came to mind.
Unfortunately after reviewing the various settings, I don't think this
is possible with just an option tweak.
It IS possible if you override the indent plugin of the java filetype.
I suggest defining your own function and placing it in ~/.vim/after/
indent/java.vim
Also in this file, set the indentexpr option (locally) to your
function.
This function will return the value of GetJavaIndent() under most
circumstances, but you can then override this value in the specific
cases you need.
See :help 'indentexpr' for help in creating this function. You will
need to find a way to match the specific cases you are looking for.
Sadly, this may not be easy to set up, but once it is, you don't need
to do it again.
This is what I have for C files, but I did it long enough ago that I
cannot for the life of me remember what it is for or how it works
without studying it for a while. It may be helpful as a starting
point, but no guarantees:
