JDK: Java(TM) SE Runtime Environment (build 1.7.0_05-b05)

I’m getting data from a REST webservice over HTTPS, and for days now it’s been fine.

I upgraded to Ubuntu 12.04 (from 11.10) over the weekend – and now this fails. I can only assume that something changed in my JVM during that time. I had thought I was on Java 7 before, so I’m very confused.

Either way the code that is fails on is the Net::HTTP.start part of:

require "net/http"

Net::HTTP.start(uri.host, :use_ssl => true, :ca_path => "/etc/ssl/certs") do |http|
  #...
end

And the error is:

OpenSSL::SSL::SSLError: Certificates does not conform to algorithm constraints
    from org/jruby/ext/openssl/SSLSocket.java:180:in `connect'
    from /opt/jruby/active/lib/ruby/1.9/net/http.rb:799:in `connect'
    from org/jruby/ext/timeout/Timeout.java:103:in `timeout'

    from /opt/jruby/active/lib/ruby/1.9/net/http.rb:557:in `start'

Any help would be appreciated.

EDIT:

I just tested this on Java 6, and it worked fine.

I’m wondering if it has to do with: https://forums.oracle.com/forums/thread.jspa?threadID=2405379
