Eclipse internal error while initializing Java tooling

Question

I am getting errors from Eclipse Indigo running on Windows 7 Ultimate. For each of the following items:

Android SDK content loader
Building workspace
Initial         


        

Answer 1

My issue was caused by some old Java projects using an old JRE System Library, so all I had to do was remove the old library and add the new one by right clicking the project -> Properties -> Java Build Path -> Libraries -> Add Library.
