Cannot load GKL with java 11 on OSX Mojave

I'm unable to load the GKL dylibs when running under Java 11. I'm not sure if this is specific to OSX or if it is true for linux too. I get the following error:

It seems like this is a new "feature" from apple to prevent you from running any code that hasn't be submitted to apple for notarization, but it only seems to apply when running java 11 at the moment and not to java 8.

Huh, this seems to be an openjdk bug that's being actively worked on and should be resolved for mojave adoptium/temurin-build#1211.

It was triggered by enabling some sort of additional osx security feature, which is optional now but is going to be mandatory in the next version of osx. So this will probably re-ocurr in osx 10.15.
