I'm trying to understand what you mean in the final sentence as there is 
currently no support for compiling or deploying agents as named modules. 
It was prototyped during JDK 9 but hasn't been a priority to come back. 
If support were to be added then it might require the agent (in its 
module declare) to export the package with the entry point to 
java.instrument but this has no impact on the modifiers of the agent 
class or premain method, they would both required to include "public".
