Cannot upload to Structurizr API using Java 11: SSLHandshakeException: Received fatal alert: handshake_failure

[gdubya]

This isn't a problem with Structurizer, per se, but calls to the Structurizer API fail when using Java 11 due to missing (?) certs in the OpenJDK distribution (discussed more here: https://www.reddit.com/r/java/comments/8y2hpj/openjdk_missing_certificates/e29lg4s).

This could be resolved by changing the certs used by api.structurizr.com, or by adding the certs to one's own JDK.

Tested using OpenJDK Java 11.0.1

Workaround: Downgrade Java to 1.8, then the examples work fine 👍

Thanks for letting me know. The cert installed at api.structurizr.com is a CloudFlare issued certificate, so hopefully this will get resolved further upstream at some point as it will likely impact a lot of other sites.

Oh, Cloudflare? Then if it was a general Java 11 problem I would have expected a much bigger fuss by now.

Looks like the problem is actually a compatibility issue with the HttpComponents dependency. Upgrading this to the latest release (currently 5.0 beta) should resolve the issue.

See https://hc.apache.org/news.html#a22_October_2018_-_HttpComponents_HttpCore_5.0-beta5_released

Can you please release the 1.1.1? Current version doesn't work with Java11, which doesn't make sense as the fix is already in the master branch

v1.2.0 is now being released to Maven Central.
