I finally found the problem.
In my project I am using a third party library that uses some other third
party library for reading ICO files. It was a class in this file that was
throwing a NPE. I have no idea why that class was being referred anyway
because I am not using ICO files at all. So I surgically remove those
classes for the jar and it worked.
I couldn't figure out how to debug the compile part in Eclipse. So I
converted the project to Maven format and loaded it up in Netbeans. But
when I loaded it up there, the exception was not thrown at compile time. I
was thrown at run time!
It was bad. I wasted all my weekend on this stupid problem.
