Yes, theoretically you should be able to use the second parameter on
Json.parse Json.stringify for conversion back and forth between java
collections and js primitives. In this model, your javascript code needs to
use Java collection APIs.

keep in mind that Arrays.asList won't let you go out of bounds.

We are not working on @JsConvert right now. JsConvert is just convenience
and you can mimic it:
@JsType(isNative=true)
interface MyType {
@JsConvert(ListConverter.class)
List getMyArray()
void setMyArray(@JsConvert(ListConverter.class) List array)
}
is roughly equivalent to:
@JsType(isNative=true)
interface MyType {
@JsProperty(name="myArray")
Object[] getMyArrayInternal();
@JsOverlay
default List getMyArray() { return Arrays.asList(getMyArray()); }
@JsProperty(name="myArray")
void setMyArrayInternal(Object[] array);
@JsOverlay
default void setMyArray(List list) {
setMyArrayInternal(array.toArray());
}
}
