> Following what is defined in the [Collections javadoc|https://docs.oracle.com/javase/9/docs/api/java/util/Collections.html#synchronizedList(java.util.List)],
it might be a good idea to synchronize when iterating the stream list, that is created with
Collections.synchronizedList.
> This work originated after the pull request submitted to VALIDATOR-434, and searching
other components in commons using similar method to create lists but not synchronizing the
iteration.
