I've come across this build error while trying to build various extensions
{code:java}

Seems like it was missed during [MINIFICPP-1319 Stream refactor|https://github.com/apache/nifi-minifi-cpp/commit/3a1a35b89e8d930dde43b3b18a1bdf990d10cc01] and since there is no CI for this extension, it went unnoticed.
