That was an interesting piece of information I did not know. That could be used to resolve issue 2. However, it does not resolve issue 1, which is that this code must be called somehow for static libraries nevertheless.

That is possible. It could be just that I have failed to locate the documentation about this. I did find about the static initializer fiasco, and I have studied when JNI_OnUnload happens (answer: basically it doesn't), and what I have found about DllMain has not been very specific, so I'm not too hopeful that it is indeed well defined.
