[Bug] infinite iteration over blobList

Query/Question When I’m calling following code

    PagedIterable<BlobItem> items = azure.listBlobsByHierarchy(path);
    ArrayList<String> strings = new ArrayList<>();
    for (BlobItem item : items) {
      strings.add(item.getName());
    }
    return strings;

it cames out that loop is infinite, constantly repeating item1 → item2 → item3 → item1 → …

Why is this not a Bug or a feature Request? It doen’t look like a bug because I can’t reproduce it in clean environment. My custom environment is plugin for browsing Azure Blob Storage in IDEA.

Setup (please complete the following information if applicable):

• OS: Manjaro Linux, 19.0.2, kernel 5.5.8-1-MANJARO
• IDE : IntelliJ
• Version of the Library used: 12.5.0

If we follow the instruction listed in the above IntelliJ plugin thread, then Jackson is able to use the ServiceLoader:

Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());

not sure this is the optimal solution for plugin though.

Just FYI, I experience this issue when upgrading from jackson-databind 2.11.4 (Dec 2020) to 2.12.0 (Nov 2020) c.f.

I’ve experienced this same issue upgrading to 2.12.0, the problem seems to be that the default behaviour in that version has changed (https://github.com/FasterXML/jackson-dataformat-xml/issues/411) and for an empty block, it now returns an empty string instead of null. I don’t think there’s a way to inject a custom SerializerAdapter. The fix should be fairly trivial to implement in JacksonAdapter#JacksonAdapter and configure the parser to behave as expected.
