When deleting a document XWiki serialize it all in XML before storing it in the trash and looks like it does not have enough memory to generate this XML.
Are you sure your memory setup is applied ? 14000m looks a lot and should have no issue to serialize even such a document. Maybe you have something else taking a lot of memory and this group serialization make it visible. One thing you could do is to take a memory dump when getting the OutOfMemoryError to see where the memory goes exactly. You can use -XX:+HeapDumpOnOutOfMemoryError to generate the dump automatically when getting a OutOfMemoryError.
