svn update -r of single file deletes the file

Question

I wanted to revert a single file to a specific revision. I quickly found an answer that might have been the perfect way to do so, but it doesn't work as expected.

The command svn diff -c 36118 path/to/MyFile.java outputs

Index: path/to/MyFile.java
===================================================================
--- path/to/MyFile.java   (revision 36117)
+++ path/to/MyFile.java   (revision 36118)

                }

+               List<String> list = createMessageList(s, 4);
                Exception exception = null;

and so on. You clearly see that from revision 36117 to revision 36118 I only changed some lines but neither added, removed or renamed the entire file. However, as I run

svn up -r 36117 path/to/MyFile.java
Updating 'path/to/MyFile.java.java':
D    path/to/MyFile.java
Updated to revision 36117.

subversion deletes MyFile.java. Why? I don't understand what is going on ...
