I suspect this is because the source is absolute and things are weird for whatever reason.

Here is the stack trace:

    Error loading source:
    Could not load the source for http://localhost:8080/examples/basic-jsx-external/example.js.
    Error: "example.js" is not in the SourceMap.

No error message now, but example.js isn't seen in the debugger at all.
I only tried the new debugger.
This might be the same as the systemjs problems, where source mapping isn't
done properly for script tags.
See bug 1223439.
