This GWT library is source right? That means it is compiled by the compilation session of MyApplication right?

Unless.... (light bulb goes on)

In some cases you want the library to act as JS library for one Page but for another page you only plan to link it with the GWT MyApplication (and not export is as a JS library) where normal optimization techniques apply.

Is that it? If so tricky...

So I don't get it. What am I missing?

The library exists as GWT library (*.jar file with *.gwt.xml) so you can use it right away in your GWT app, but the library is also exported by the library maintainer to JavaScript so that JavaScript people can also use it right away by including a *.js file.

In that case your app does not want to use -generateJsInteropExports because it directly uses the GWT library which has @JsType(isNative = false) all over the place in its Java files. If you would use -generateJsInteropExport in your app, it would have a negative impact on your code size because these @JsType classes would not be optimized/pruned then. Now imagine you have several of such libraries in your app.
