certificate used for https not trusted by JVMs older than java 8 b101

[jhpoelen]

If I understand it correctly, the fishbase api generated certificates using https://letsencrypt.org to support https. Unfortunately, most JVMs do not yet trust the Let's Encrypt root certificate.

from http://stackoverflow.com/questions/34110426/does-java-support-lets-encrypt-certificates

Update 2016-08-05: Java 8u101 has been released and does indeed include the IdenTrust CA: release notes

So, the hopefully the issue will go away eventually.

This is what the error looks like:

Thanks, yup, that's annoying, though like you say best addressed on their end. Thanks for linking to the stackoverflow post, looks like the issue is resolved for the latest java versions anyhow?

[jhpoelen]

@cboettig Yep, most recent version of oracle java 8 jvm fixes this. I guess I just needed to vent a little ; ) .

Would it be an idea to mention this the fishbase api readme and point to this (now closed) issue?

[sckott]

@jhpoelen yep, can do that
