package p;
class A{
	native void m(int i);
}

i get an NPE when i call resolveBinding on the declaration of 'i'
(the CompilationUnit node was created with resolveBindings == true, 
if that makes a difference)

java.lang.NullPointerException
	at org.eclipse.jdt.core.dom.DefaultBindingResolver.resolveVariable
(DefaultBindingResolver.java:297)
	at org.eclipse.jdt.core.dom.VariableDeclaration.resolveBinding
(VariableDeclaration.java:92)

In this case, I guess you expect null to be returned.

when creating regression tests for it - please include also this one:
abstract class A{
	abstract void m(int i);
}

this one is meybe related 
(resolveBinding on the SimpleName 'k' inside the qualified name 'j.k'):

class A{
	int k;
	static class j{
		static int k;
	}
	void m(){
		int y= 0;
		j.k= 0;
	}
}	

stack trace is different:

another test case for your collection :)

(resolveBinding on the declaration of 'i')
interface A{
	 void m(int i, int j);
}

I forgot to connect the name inside a SingleVariableDeclaration. So it was 
impossible to retrieve the compiler node corresponding to a method parameter.
Fixed and released in HEAD.

Fixed.
