Just a note to anyone experimenting with OpenJ9. When trying to make requests to https sites from my server using clj-http I'd get an error like this:
Syntax error (SSLException) compiling at (myapp.clj:485:1). Received fatal alert: bad_record_mac
Updating to a more recent OpenJ9 (openj9-0.11.0-11.0.1) fixed the problem. Posting this here so it's findable on the web for anyone googling the problem. Probably also applies people writing Java as well as to people writing Clojure.
Note: Why OpenJ9 instead of OpenJDK? Because it uses approx 40% less RAM, so hosting is cheaper.
