I could not reproduce it in latest. Here is my test case. Tell me if you think this is close enough from your test: <source> package test0304; interface Test { public void foo(int arg); } </source> I will try again with your test case, but I think this is an old problem.
Forgot my previous note. I reproduce it. I did the initial parsing with: AST.parseCompilationUnit(source, true) instead of AST.parseCompilationUnit(source, false). Big difference! I am looking at it.
The bug comes from the fact that the interface method is not tagged as abstract. Therefore I am trying to retrieve the position of the closing brace. And of course I don't find any. When I try to set the source range with invalid positions, I got the exception.
Fixed and released in HEAD.
Fixed.
