Allon Mureinik has submitted this change and it was merged. Change subject: webadmin: Remove Linq#cast ...................................................................... webadmin: Remove Linq#cast Linq#cast redundantly creates a new ArrayList with the same objects as the source collection has. This is, at best, an O(n) operation and usually even worse, as the ArrayList's internal array needs to be reallocated several times. This patch removes the calls to Linq#cast in TemplateStorageListModel and replaces them with the proper use of generics where a new collection is not needed, or with a straight forward call to new ArrayList<>(source) (which has a fixed O(n) performance guarantee) where it is. Note that in many cases the usage of Linq#cast was in a boiler-plate for-loop that may have been replaced with a more elegant usage of Java 8's streams, but that's beyond the scope of this patch.
