The Dalvik classloader (probably) pranking me

Question

I have the following code in Android 4:

import org.bouncycastle.jce.exception.ExtCertificateEncodingException;
....
public void method(){    
   try { 
   throw new ExtCertificateEncodingException();

   } catch(ExtCertificateEncodingException e){

   } 
}

I compiled it and ran it. And an exception was thrown but it wasn't catched. It was confused me a bit. But, after an investigation it turned out that e has type com.android.bouncycastle.jce.exception.ExtCertificateEncodingException (or something like that) instead of bouncycastle.jce.exception.ExtCertificateEncodingException.

And, I don't understand that exactly. I suppose that class loader makes some magic that I cannot understand. After all, I imported: org.bouncycastle.jce.exception.ExtCertificateEncodingException.

1. Please help me understand it, explain it.
2. Why a classloader is not obey and doesn't load it? (I am not sure if my interpretation of that behaviour is ok).
3. Why I cannot import com.android.bouncycastle.jce.exception.ExtCertificateEncodingException
4. How to catch exactly it? I am not interested in catch(Exception e)
