Short answer is: I don't know. Corretto is certainly the easiest way to get a 
JRE/JDK for Amazon Linux, and it should be a drop-in replacement for anything 
else you're using.

Only if you need cron. We use it to periodically post some measurements to 
CloudWatch in some circumstances. If not, don't worry about it.

Yep.

Thanks Paul, that’s really helpful.

java -version
openjdk version "1.8.0_402"
OpenJDK Runtime Environment (build 1.8.0_402-b06)
OpenJDK 64-Bit Server VM (build 25.402-b06, mixed mode)

Will I need to change to corretto?

Sounds like I will need to look into cronie, thanks for the heads up.

Is the WO apache adaptor going to work as is?
And wotaskd and javamonitor should be fine I guess as just java apps.
