so far I think we've been using 4 spaces mainly in Java even if currently we have a mix. I would prefer spaces for all.

+1 I have a preference for spaces ; FYI, it seems that google in its guidelines goes this way (https://google.github.io/styleguide/javaguide.html#s2.3.1-whitespace-characters), but the default eclipse (which might follow oracle official guidelines) uses tabs.

The guideline also use 2 spaces only (https://google.github.io/styleguide/javaguide.html#s4.2-block-indentation) maybe that's better too ?
