Description

gson-extras class GraphAdapterBuilder depends on internal Gson classes:

gson/extras/src/main/java/com/google/gson/graph/GraphAdapterBuilder.java

Lines 25 to 26 in 9793828

	import com.google.gson.internal.ConstructorConstructor;
	import com.google.gson.internal.ObjectConstructor;

Maybe this could be solved by exposing Gson functionality for creating new instances, see for example #1968.
If that is not possible, another solution would be to add a module-info.java to gson-extras and to change gson's module-info.java to export the internal packages exclusively to the gson-extras module.
