Issue mapping method in AIC from Eclipse to WALA

[khatchad]

I am unable to use com.ibm.wala.cast.java.translator.jdt.JDTIdentityMapper.getMethodRef(IMethodBinding) to look up a method declared in an AIC. Here's an input example that causes this error:

class A {
    void m() {
    }
    
	pubic static void main(String[] args) {
		new A() {
			@Override
			void m() {
				new ArrayList().stream().count();
			}
		};
	}
}

The input method is the m() declaration inside the AIC. Here's the client code:

MethodDeclaration mDecl = // ...
JDTIdentityMapper mapper = getJDTIdentifyMapper(mDecl);
MethodReference methodRef = mapper.getMethodRef(mDecl.resolveBinding());

And stack trace from a test I ran:

-- Error Log from JUnit --
Method: testAnonymousInnerClass
Actual: null
Expected: null
Stack Trace:
java.lang.NullPointerException
