RFR: 8369817: [TESTBUG] EmptyPath::toString is ignored

[Francesco Andreuzzi]

JUnit ignores `@Test` methods which do not return `void`:


(1) [WARNING] @Test method 'public java.lang.String EmptyPath.toString()' must not return a value. It will not be executed.
    Source: MethodSource [className = 'EmptyPath', methodName = 'toString', methodParameterTypes = '']
            at EmptyPath.toString(SourceFile:0)


I propose to amend the method signature. This looks trivial to me.
