Can't build JRuby with J9

[zzak]

My good friend @headius pointed me to report this issue here, so here we are.

I'm having issues building JRuby, both 1.7 and 9.0.4.0 using the latest j9 pre-release binary.

Here's the output I'm getting when trying to use ruby-build to install the latest JRuby 9000:

~ => export JAVA_HOME=/home/zzak/src/jre-9/
~ => ruby-build jruby-9.0.4.0 ~/.rubies/j9-jruby-9

Also, interesting that it says unsupported Java version "9"..

Here's the log from the JRuby 1.7 build (which is missing the unsupported Java version bit):

I can reproduce it, will look into it . . . .

@mkristian How did you setup j9?

I downloaded an early access release from here: https://jdk9.java.net/download/
Then set JAVA_HOME to the extracted tarball directory.

Maybe I missed a step?

[mkristian]

@zzak thanx for the link. I did use an early access version from the oracle.com website.

I can reproduce it without ruby-build by just using jdk9 on the github build (both master or jruby-1_7 branch)

bin/jruby bin/gem install jruby-launcher

the "unsupported Java version" comes from version check in RubyInstanceConfig.java jruby/jruby#3563
