title: Finding Java classes and/or methods unsupported by GWT
body: <p>I want to use a third-party library, for which I have the source code, in my GWT project. </p>
  
  <p>Right now, it's failing with the well-known "No source code is available for type...; did you forget to inherit a required module" message. I understand that error to be caused by the dependence of the third-party library on a class/method that is not emulated by GWT.</p>
  
  <p>I'm in a pickle because the GWT compiler does not inform me which class/method in the third-party library is causing it to barf. I kind of expected that a lint-like tool for finding unsupported Java constructs would be included in Google's GWT downloads, but I can't find it.</p>
  
  <p>Any suggestions?</p>
