   To submit a breakpoint via JDI we need the class name and line number.
   In case of Java, if everything goes well then the correct class name is retrieved from nb-javac based on the source file and line number. The class name can not be found for other non-Java bytecode-based languages. I've recently fixed that for Groovy, where I'm retrieving the class name from the Groovy parser.
   
   I had a request in a distant past to be able to submit line breakpoints just based on a class name and line number, so that you can add breakpoints to classes you do not have sources from. It was never implemented and it's a bit unusual to know a source line number when you do not have the sources. This case seems to be somewhere in between. You have the source, you know the line number, but the system is unsure about the correct class name to submit the breakpoint to.
   
   It'd not be much pleasant way of work, if you need to adjust class names of all breakpoints you create. Thus this can be seen as an emergency correction when the autodetection fails or is not present because of an unknown language.
   As this is something the user should not need to change, I'd shade it by default and prepend a check-box that would make it active. In any case, it's preferred to correct the class detection mechanism when such an issue appears.
