STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create new ConcurrentHashMap and put 1000 entries to it, with keys=1,2,3,...,1000 and all values=0.
2. Start 2 parallel threads:
- First thread: for i=1,2,3,...,1000 puts an entry (k=i, v=1) into the map;
- Second thread: removes all `0` from the map: `map.entrySet().removeIf(e -> e.getValue() == 0)`.
3. Check size of the map. 


EXPECTED VERSUS ACTUAL BEHAVIOR :

To adhere to guidelines or requirements, API designers may want to control how JSON/XML responses are formatted. Spring Web makes use of Jackson to perform JSON/XML serialization. Therefore, to customize our output format, we must configure the Jackson processor. Spring Web offers XML-based or Java-based approaches to handling configuration. In this article, we will look at the Java-based configuration.

Enable XML output
First of all, if you have created your project through https://start.spring.io/ you need add the following dependency to your project because there is no XML serialization by default:

<dependency>
	<groupId>com.fasterxml.jackson.dataformat</groupId>
	<artifactId>jackson-dataformat-xml</artifactId>
</dependency>
ok, now we can investigate the output customization process. Imagine we have this REST controller:

  /**
     * Recursively compare the contents of the directory of downloaded
     * files with the contents of the "ground truth" directory.
     */
    public static void recursivelyCompareDirectories(File expected,
                                               File generated)
            throws IOException {
        // Checks parameters.
        assertTrue("Generated Folder doesn't exist: " + generated,
                generated.exists());
