A DESCRIPTION OF THE PROBLEM :
The Server JRE is missing two modules that are quite common for server applications:
- java.corba
- java.se.ee

The modules are included in the regular Oracle JRE, JDK and OpenJDK

REGRESSION. Last worked in version 8u144

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run java --list-modules

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expect the list to contain
- java.corba@9
- java.se.ee@9

ACTUAL -
Both modules are not listed in the Server JRE. They are listen for the JRE and JDK

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Switch from Server JRE to JRE. This increases the disk footprint and attack vectors on servers.
