[romani]

I am not sure that we need to change variables like GT, ...

[mkordas]

Of course short-named public variables from api package need to be suppressed for now.

Maybe GT is fine, but I would have no idea what does e.g. SR (shift right) mean without looking into documentation. SHIFT_RIGHT would be much better.

[romani]

I am agree on SR.

@mkordas ,

Please share your thought on naming of following problematic variables: ex, sb, it, id
They are pretty well spread.

Should we stay with minimum size 2 or 3 ?

[romani]

http://checkstyle.sourceforge.net/config_naming.html#LocalVariableName should be reconfigured to catch variables who are less then min size (in default form it allow one-char variables).

[romani]

I mark issue as resolved, for now we have limit 2 for names , discussion for #985 (comment) could be continued in this issue.
