Code in method is not called completely

Question

I have a method in Java which is called from jni:

public static void CallDoSomething()
{
    Log.i(LOG_TAG,"A");
    Log.i(LOG_TAG,"B");
    something.DoSomething(); 
    Log.i(LOG_TAG,"C");
    Log.i(LOG_TAG,"D");
}

So, the first line is called, I get 'A' in the logcat, after that nothing. No 'B' or the log from DoSomething() or 'C' or 'D'. It is really weird. I cleaned the project, restarted the IDE, nothing helped. No exceptions are made and the app doesn't crash.

Why is the log file missing entries of B, C, and D?
