JDK or JRE for Mule 4 Standalone Runtime?

Question

Hi All,

The documentation states the the JDK should be used for the Mule 4 standalone Runtime: https://docs.mulesoft.com/mule-runtime/4.1/runtime-installation-task

Before downloading and installing Mule runtime, verify that you have Java SE JDK 1.8 installed

Why is the JDK needed? Can you use just the JRE instead?

Thanks, Steve

I remember reading something about this about a month ago but I can't seem to find it again. Basically the JDK has more functionality and includes more files/libraries than the JRE does. Anypoint will run with just the JRE but certain things will give you errors if you try and use them (if I remember correctly there is some debugging that you simply cannot do without the JDK). I would strongly advise using the JDK and not the JRE.

Thanks for your answer :)

I understand why the JDK is needed for the Anypoint Studio (as you are "developing"), still think it is strange to use the JDK for the Runtime though.

Yes true and JRE is the one use for Run-time and as the tooling requires both JDK/SDL with run-time libs.
