However, the motivation isn't clear as there isn't an issue with JCE providers in java.base using native code. I know there were non-technical issues with libsunec in the past but that would haven't prevent the SunEC code form being compiled into java.base.

Another way to solve that issue is that delay verification of signed JARs until the boot layer is created - if we did that, would you still want to move the SunEC provider into java.base?


Curious, the provider mechanism provides a level of indirection, aka 
service, a boundary or separation.  How are module boundaries defined?
