Just missing the appropriate support so that Object#hashCode is not invoked (the hash code is defined for all objects in Java, unlike Python). Simply following the example of PyByteArray (which implements bytearray), we get the following patch:

+    @Override
+    public int hashCode()
+        return array___hash__();
+    }
+
+    @ExposedMethod
+    final int array___hash__() {
+        throw Py.TypeError(String.format("unhashable type: '%.200s'", getType().fastGetName()));
+    }
+

Just need to add a test to complete.
