[Bug classpath/27128] New: Collections.unmodifiableMap() can be modified

[david dot gilbert at object-refinery dot com]

For an unmodifiable map created using Collections.unmodifiableMap(), it is
possible to modify an entry by obtaining an array of the map entries:

Object[] entries = umap.entrySet().toArray();

...then modifying the entries from the array:

((Map.Entry) entries[0]).setValue("XYZ");

I committed a Mauve test for this a few minutes ago.
