The hermetic-java-runtime branch doesn't have general symbol hiding enabled. That's why I'm wondering what the issues are with these libs except for `libjawt` with the current PR. 

(A side-note on `libjawt.a`: For static linking, we don't need `libjawt.a` and the headless or headful libs can be directly statically linked with.)

Right, that would be a good & practical way to add the support in the mainline.
