I skimmed through this.

The module-info.java looks okay. The permission check idiom in 
JVMCICompilerFactory (and EventProvider) look fine.

I'm not sure about using RuntimePermission("jvmci"). One reason is that 
RuntimePermission specifies in its javadoc all the possible targets. It 
might be better to just introduce a new basic permission for this.

One thing about Services.load is that it uses ServiceLoader.load and 
hence the TCCL. I don't know if this is what you here, I suspect you 
want the system class loader.

In passing, the @return for getTrivialPrefixes() suggests an empty array 
can be returned and so I assume the default should be to return an empty 
array rather than null.
