There is currently no documentation on moving from Oracle java to open JDK. I worked with support to convert over. This is how we did it:
Jamf currently supports open JDK 8. Jamf will add future support for open JDK 11
Download the latest version of Open JDK 8 from https://adoptopenjdk.net/releases.html (V8, Hotspot, this one is recommend by jamf. JDK includes JRE)
Install Open JDK:
Uncompress JDK zip to temp directory (should have a directory name something like this jdk8u192-b12)
Copy directory to C:Program FilesJava
Stop Tomcat (ServicesTomcat8)
Edit Windows Environment Variables to point to the correct JDK/JRE java directories
JAVA_HOME C:Program FilesJavajdk8u192-b12
JRE_HOME C:Program FilesJavajdk8u192-b12jre
Change Tomcat Java Settings:
Launch Tomcat settings app: C:Program FilesJSSTomcatin omcast8W.exe
Change Java Virtual Machine setting to target correct JRE dll C:Program FilesJavajdk8u192-b12jreinserverjvm.dll
Set memory
Initial Memory Pool 512
Maximum memory pool 1024
Go to add and remove programs. Remove older versions of Java JDK and Java JRE.
Restart tomcat.
Test

Note I have a support ticket open with Jamf. The windows Jamf installer (MSI) will not upgrade on a system using Open JDK. It says there is no java SE development kit installed.
