Oracle Java and Open JDK are out of date

[Mattwmaster58]

Hi, in tracking down some discrepancies between sslyze and other tools, and it looks like Open JDK and Oracle Java certificate stores have fallen out of date because of this: https://github.com/nabla-c0d3/trust_stores_observatory/blob/master/main.py#L55-L58

As far as I can tell, bringing back support for these sources would require these two things

1. automatically parsing the latest JDK download URL
2. Parsing PKCS12 that Java now uses (over JKS)

Is this something you would like some help with? It's something I could give some time to.
