This is in response to some older posts. If your HashSet.jni.h file is giving you problems, you need to first make sure you are using JDK 6. Then, if you don't want to lose your progress, instead of resetting your entire build with a "make clobber", you can just remove the <E>'s wherever they are. I did it to mine and it kept right on building. Or, better yet, you could just paste in my HashSet_jni.h as follows:
