// testUnusableMethodName.js

// For any function, the property 'name' is an unwritable property.

// The value returned by java.import(<classname>) is a constructor-like function that has the shape of the class.

// In particular, any static methods of the class will be added as properties of the function.

// If a class has a static method named 'name', then an exception woudld be thrown when

// node-java attempts to set assign the static method to the .name property of constructor-like function.

// As a workaround, node-java will append the `ifReadOnlySuffix` to the property name.
