Environment

• jruby/jruby cloned at c911af4
• java 9 installed with homebrew-cask
• macOS 10.12.6

Expected Behavior

Building complete JRuby jar succeeds.

Actual Behavior

Building complete JRuby jar on Oracle JDK 8 succeeds, but fails on Oracle JDK 9. The output refers to SSL issues like this:

Caused by: org.jruby.embed.EvalFailedException: (OpenSSL::X509::StoreError) setting default path failed: No password supplied for PKCS#12 KeyStore.

Full compile log is available at gist.

Notes

My first thought was that it's my environment issue. However, when I downgraded Java to 1.8.0_144, JRuby was built successfully, which makes me think it might be a different problem.

Mentioning #4111 as a main issue to track.
