Building a plugin on top of JFluid (profiler)

Hello,
 I am attempting to build a NetBeans plugin that use the profiler, specifically the classes in "Java Profiler (JFluid).” I noticed that this doesn’t appear to be a public API. I initially got an error about not being a “friend” which I managed to circumvent by selecting “Implementation Version” in the module dependency dialog. 
 My question is, are there any ramifications for creating a plugin that depends upon a JFluid module? 

Thanks,
-Ryan
