Right, no splitting of package javax.annotation between the class path 
and module java.annotations.common (the Java SE subset of the JSR-250 
defined "Common Annotations"). To upgrade/override this to the EE 
version means requires deploying the EE version as a module 
-upgrademodulepath.

As you've read in the various threads, we are trying to get to the point 
where the 6 modules shared with Java EE are not resolved by default. 
When we get there then you should be able to put a JAR file on the class 
path with javax.annotation.* types and it should work as there will be 
no overlapping with packages in modules. Alternatively, deploy the EE 
version of module java.annotations.common on the module path, that will 
work too.
