I have a project where breakpoints worked well for .jsp included in other .jsp.
Recently, I have renamed all .jsp fragments to .jspf to avoid incorrect validation.
The problem is that now breakpoints are ignored in .jspf.
It strange because it supposed to be fixed by https://bugs.eclipse.org/bugs/show_bug.cgi?id=334150
However I can still "step into" an included jspf, if I put a breakpoint in the containing jsp page (before include).
