These error messages appear when I run my Application. It doesn't affect the execution of the application though. The app is based on Android 4 ( API Level 14), it has some code to call a web service, and the build path has http-commons library.

If you google for initializeJavaContextClassLoader NullPointerException you'll find you are definitely not the only one running into this. The solution isn't really clear though.
Have you tried doing a Project -> Clean and rebuilding?

My app crashes when I try to open in. The only change I've made was adding a .ogg file to my res/raw directory. It's really weird. I haven't added any codes or made any other changes. I just dragged a sound file into raw and compiled. It just keeps saying "unfortunately blah has stopped". Are there any obvious things I should check?
MainActivity.onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.engine_layout);
myEngineView = (EngineView) findViewById(R.id.engineviewid);
myEngineView.setKeepScreenOn(true);
}
I get this in logcat:

I've put breakpoint at line 125. Surprise - LogCat show exception without reaching breakpoint.
Code in onCreate is:
super.onCreate(savedInstanceState);//line124
m_current = MyApp.sInstance.GetName();//line 125 ========
Update
sInstance is App singleton.
added correct log copy
Update2
Bigger stack trace provided

If there is anything anyone can do to help, I would greatly appreciate it.
Your activity probably extends ListActivity and because of this in your xml file containing the layout of your activity(the one you set with setContentView(R.layout.name_of_layout)) you must have a ListView element with the id:
<ListView android:id="#android:id/list"
//other attributes
>

i got this error when im run my application.... help
Check your manifest file to make sure that the activity nhexia.pack.SaturnVTDActivity is declared correctly.
Its also possible that you updated the ADT plugin and need to move your includes around as this link suggests.
It seems that you try to launch a class which cannot be found. Is the activity defined in the manifest, is the class misspelled?
Try debug in eclipse and see what line it fails on, and share that in here.

You are trying to use a reference to null (e.g. variable uninitialized, etc..) in CameraMap.GalleryCamera,onCreate() method, line 20.
Please post code for this method (and indicate line number 20).
