'for' loop may be replaced by 'while' loop

Reports a for loop that contains neither initialization nor an update component. Suggests replacing the loop with a simpler while statement.


for(; exitCondition(); ) { process(); }

After the quick-fix is applied the result looks like:

while(exitCondition()) { process(); }
