Thanks for all the answers
The Collection#toArray does not work in my case because dataTables.net are
a bit sensitive in the input. It stumbles upon java.lang stuff later on.

1.
buttons:
1. 0:"copyHtml5"
2. __elementTypeCategory$:6
3. __elementTypeId$:2
4. java_lang_Object__1_1_1clazz:java_lang_Class_Class__V
5. java_lang_Object_castableTypeMap:Object
6. java_lang_Object_typeMarker:
com_google_gwt_lang_Runtime_typeMarkerFn__V()
7. length:1
8. __proto__:Array[0]
2. buttons2:Array[1]
1. 0:"copyHtml5"
2. length:1
3. __proto__:Array[0]
About Array vs []
I am not js expert and looking for the difference I hit this

Check this answer

So I though if that could work with GWT and I tried it.
Also thanks for the link I bookmarked it.
