The sniper printer does not behave as expected when an invocation is replaced by another invocation.

Hi all,

I have the following code:

String argStr = args.toString();

And I wish to transform it to:

String argStr = Arrays.toString(args);

However, with the Sniper printer (but not with the default one) I get:

String argStr = args.toString(args);

No exception is thrown, but the printed code is not the expected one.

I hope that the following failing test case helps to find the actual issue:

        @Test
	public void testPrintReplacementOfInvocation() {
		testSniper(InvocationReplacement.class.getName(), type -> {
			CtLocalVariable localVariable = (CtLocalVariable) type.getMethodsByName("main").get(0).getBody().getStatements().get(0);
			CtInvocation invocation = (CtInvocation) localVariable.getAssignment();
			CtExpression prevTarget = invocation.getTarget();
			CtCodeSnippetExpression newTarget = type.getFactory().Code().createCodeSnippetExpression("Arrays");
			CtType arraysClass = type.getFactory().Class().get(Arrays.class);
			CtMethod method = (CtMethod) arraysClass.getMethodsByName("toString").get(0);
			CtExecutableReference refToMethod = type.getFactory().Executable().createReference(method);
			CtInvocation newInvocation = type.getFactory().Code().createInvocation(newTarget, refToMethod, prevTarget);
			invocation.replace(newInvocation);
		}, (type, printed) -> {
			assertIsPrintedWithExpectedChanges(type, printed, "\\QString argStr = args.toString();", "String argStr = Arrays.toString(args);");
		});
	}

This is the content of the InvocationReplacement class:

package spoon.test.prettyprinter.testclasses;

public class InvocationReplacement {

	public static void main(String[] args) {
		String argStr = args.toString();
	}

}

I believe this issue was solved, thus I'm closing it.
