Review comment:
This is very weird. You do not have to initialize the IdGenerator.
That is, `utils::IdGenerator::getIdGenerator()` is a singleton factory
function: the first time you call it, it creates a function static IdGenerator
and returns it. This thread safe, protected by the function static
initialization.
After this, if you want (and in normal usage, you want), you can call
`initialize` on the IdGenerator, supplying it properties, so that it can
configure what method should be used for ID generation. This is not a thread
safe function, and is called in both `MiNiFiMain.cpp` and in `TestBase` as one
of the first things, before other threads are started.
However, this is not a required step: if you don't call `initialize` it will
just default to the time-based UUID implementation.
`IdGenerator::uuid_impl_`, which on non-Windows platforms is a handle of the
third party UUID implementation we use (OSSP UUID), is created in the
`IdGenerator` constructor, so there should be no way for it to be nullptr
(unless of course its constructor throws, or we get a bad_alloc, but we should
have seen an exception in this case).
`CoreComponent` uses the IdGenerator properly, in
`libminifi/include/core/Core.h:166` it calls
`utils::IdGenerator::getIdGenerator()` as it should, it does not store a static
pointer, as far as I can see, @msharee9
I could not reproduce this on macOS, so I am going to try to reproduce it on
Linux.
