+Summary: XmlSerializer doesn't create empty collections on deserialization
+
+Description of Problem:
+
+When deserializing object from XML, XmlSerializer doesn't create
+collections when there are no items in XML. MS Implementation does create
+the collection objects.
+
+Steps to reproduce the problem:
+1. Compile the attached program (mcs serialization.cs)
+2. Run (mono serialization.exe)
+
+Actual Results on Linux/Mono(r47826)
+
+=============
+serializedAs: <?xml version="1.0" encoding="utf-16"?>
+<root xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
+  <k>0</k>
+</root>
+d2.list1 != null: False
+d2.list2 != null: False
+=============
+
+Expected Results (as on Windows/XP, .NET 1.1)
+
+=============
+serializedAs: <?xml version="1.0" encoding="utf-16"?>
+<root xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
+  <k>0</k>
+</root>
+d2.list1 != null: True
+d2.list2 != null: True
+=============
+
+This applies to both ArrayList and custom collection classes which inherit
+from CollectionBase.
