at first , tests failed No name provided for parameter 'elemental2.core.ReadonlyArray.EveryCallbackFn.onInvoke.p0'. Name can be specified in a name mapping file. after removing some unused integer entities from elemental2, this error went away. Then tests failed //third_party/java_src/j2cl_proto/java/com/google/protobuf/contrib/j2cl/runtime:runtime Error:ByteString.java:78: Cannot cast from BigUint64Array to Uint8Array , and also

Exception in thread "main" java.lang.IllegalStateException: No declaration found for member [Property {  name: BYTES_PER_ELEMENT, type:number, inferred: false}]. Please fix the extern file. A class must implement all methods from its super interfaces.

Looking quickly at the integer_entities (for some related work, to be submitted as a PR soon), I suspect we just need to duplicate the entities found in TypedArray, as it will now be an interface, and classes that implement it now must declare the same signature, rather than just inheriting the native impl.

As an example, for these Uint8Array enjtries:

Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.copyWithin(int, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.copyWithin(int, int, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.set(TypedArray.SetArrayUnionType, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.at(int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.subarray(int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.subarray(int, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.fill(double, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.fill(double, int, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.slice(int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.slice(int, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.toString_()
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.indexOf(double, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.includes(double, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.lastIndexOf(double, int)
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.toLocaleString()

I think the following integer entities, will resolve most of the above (sorted by the order of the errors above they will resolve, not alphabetical as expected):

elemental2.core.Uint8Array.copyWithin.target
elemental2.core.Uint8Array.copyWithin.start
elemental2.core.Uint8Array.copyWithin.end
elemental2.core.Uint8Array.set.offset
elemental2.core.Uint8Array.at.index
elemental2.core.Uint8Array.subarray.begin
elemental2.core.Uint8Array.subarray.end
elemental2.core.Uint8Array.fill.begin
elemental2.core.Uint8Array.fill.end
elemental2.core.Uint8Array.slice.begin
elemental2.core.Uint8Array.slice.end
elemental2.core.Uint8Array.indexOf
elemental2.core.Uint8Array.indexOf.fromIndex
elemental2.core.Uint8Array.includes.fromIndex
elemental2.core.Uint8Array.lastIndexOf
elemental2.core.Uint8Array.lastIndexOf.fromIndex

This leaves the following, which I don't yet understand:

Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.toString_()
Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.toLocaleString()

and this, which I'm not certain will be resolved (but might be, if the union type is inherited correctly):

Error:Int8Array.java:21: The type Int8Array must implement the inherited abstract method TypedArray.set(TypedArray.SetArrayUnionType, int)
