Loading of libraries slower after update to 1.5.10 (Windows, no longer cached?)

First off thanks for all your great work. I just updated to 1.5.10 and noticed loading of libraries went from 500ms to 5 seconds in my project, I did a little bit of debugging and I get the impression it has to do with caching, with 1.5.9 I see the following debug messages when I start my app for the first time after deleting the cache (I am creating a FFmpegFrameGrabber here):

...

And with 1.5.10 I see this when running after deleting the cache:

Debug: Loading class org.bytedeco.javacpp.presets.javacpp
Debug: Loading class org.bytedeco.ffmpeg.global.avutil
Debug: Loading class org.bytedeco.javacpp.presets.javacpp

...

So it looks like libraries are no longer extracted to the cache. I will try to make some time to look into this deeper but if you have any suggestions that would be greatly appreciated, could it perhaps be that I have to configure caching myself with the new version?
