build I20070917-0010 1) create X.java public class X { void foo() { int a /*a*/, b /*b*/; for (int i /*i*/, j /*j*/;;) { } } } 2) build a DOM AST (with ASTView). The end of 'a' is after '/*a*/'. The end of 'b' is after '/*a*/'. The end of 'i' is after 'int i' and not after '/*i*/'. The end of 'j' is after ', j' and not after '/*j*/'. The end of the fragment should be the same in each case.
Do we want to include the trailing comment inside the positions ? I would say no. The comment could be included in the extended range though. David, any thought ?
My explanation wasn't clear. The problem isn't related to trailing comments. The problem is the same without comments. public class X { void foo() { int a , b ; for (int i , j ;;) { } } } Inside a 'for' statement the end of the fragment is at the end of the variable name and inside a locale variable the end is just before the next comma or semicolon. The problem is in the same area as bug 199668.
The positions should be consistent in both cases. No whitespaces should be included in the position range.
