Java Collections Unmodifiable

Collections.unmodifiable* can throw StackOverflowError errors when used recursively. For example:

Exception in thread "main" java.lang.StackOverflowError
	at java.util.Collections$UnmodifiableCollection$1.<init>(Collections.java:1039)
	at java.util.Collections$UnmodifiableCollection.iterator(Collections.java:1038)
	at java.util.Collections$UnmodifiableCollection$1.<init>(Collections.java:1039)
	at java.util.Collections$UnmodifiableCollection.iterator(Collections.java:1038)
[...]

Reproducible Source:

List<Integer> list = Collections.unmodifiableList(Arrays.asList(0, 1, 2));
for (int i = 0; i < 10000; i++) {
    list = Collections.unmodifiableList(list);
}
for (int i : list) {
    System.out.println(i);
}

Just thought that was interesting.
