Hi Robert,

sorry for the delay, but now I'm back on to this and after polishing,
I'm planning to release everything within the next two weeks.

4. I was also surprised that I needed to create an executor for the
'Healthy' event to be registered. I thought that with the eventadmin
requirement the services would be registered automatically, without me
intervening.

So no instance of HealthCheckMonitor is active by default currently.
Configuring one means that the tags as given will be regularly
executed. To be exactly in line with systemready, you would configure
an instance of HealthCheckMonitor with tag "systemready" and
intervalInSec=5. Would you have expected that this config is done
automatically for the case the event admin is present? (we
definitely cannot start monitors for all checks by default, that
would potentially be harmful)

3. I was a bit surprised that hc.core requires the Servlet API. The
systemready bundle was a bit more lightweight.

systemready had the same dependency, just optional. I created
FELIX-6289 to make it also optional for hc.core.

2. core build fails with pax-exam tests. Perhaps related to Java 11?

I checked this, it is indeed a Java 11 problem (just checked both
1.8 and 11). I'll check and fix.

1. api build fails due to the baselining check

this I could not reproduce.

Hello Georg,

Thanks for the implementation, looks good! I took it for a spin and for
my scenario it works as expected.

In addition to that. I have some notes that you may find useful.

1. api build fails due to the baselining check -
org.apache.felix.hc.api.execution: Version increase required; detected
2.0.0, suggested 2.0.1 .

Anyway, the implementation works for me and I can support both
systemready and health checks, which is great.

Thanks!
