In a scenario where C2 property update is sent after C2 debug command with the
update parameters nifi.c2.agent.class and nifi.c2.agent.heartbeat.period to a
Windows minificpp agent from a C2 server, sometimes the windows client crashes
with the following error:
{code:java}
Exception thrown: read access violation.
org::apache::nifi::minifi::core::Property::getValidator(...).**** was nullptr.
