JVM version detection breaks on Java 10

[perlun]

Very similar to #142; this has unfortunately regressed on Java 10.

$ gem install bundler
Ignoring executable-hooks-1.4.2 because its extensions are not built.  Try: gem pristine executable-hooks --version 1.4.2
Ignoring gem-wrappers-1.4.0 because its extensions are not built.  Try: gem pristine gem-wrappers --version 1.4.0

The reason why this has reappeared is because the java.version format has been changed upstream (again.... 😄)

$ java9
$ java -XshowSettings 2>&1 | grep java.version
    java.version = 9.0.4
$ java10
$ java -XshowSettings 2>&1 | grep java.version
    java.version = 10
    java.version.date = 2018-03-20

I.e. the fix in #143 is really needed for us to get working on Java 10, unless the OpenJDK team is willing to change the version to a normal SemVer version string again. (which I personally think makes sense, but I don't have the full picture there to be able to speak dogmatically about the matter.) Anyhow, going back and forth like this does not make a whole lot of sense to me.

Sigh.

@headius

Sigh.

Yeah. Do you know if it's likely that we can get upstream to fix this (again)?

[headius]

I am just going to hardcode it to use V9 for anything that isn't "1.7", "1.8", or "8". Hopefully they'll settle into a pattern before we decide we need Java 10 bytecode features.

[headius]

I've fixed this on all branches of JRuby and it will be in the next releases, whatever they may be.

[perlun]

Much appreciated @headius, thank you for this. 👏

[headius]

@kares We need to get a release out for 9.1.17. Do you have anything else you want to get in?

[kares]

fix this issue (it pbly needs to be fixed in jossl itself as well) and that the usual regression -> tests failing
... but I wasn't planning looking into any of them atm.

Java 10.0.1 has been released and they have sorted this out now:

$ java -XshowSettings 2>&1 | grep java.version
    java.version = 10.0.1
    java.version.date = 2018-04-17
$ gem install bundler
Successfully installed bundler-1.16.1
1 gem installed

[kares]

has been resolved in jruby-openssl (>=) 0.10.0.
only Java (9/10) pre-releases were really problematic, as comments already suggested.

I still see this broken withjava 11 and 9.1.17.0, it seems to be ok with 9.2.0.0 but unfortunately I need 9.1. for asciidoctorj.

Still broken here:

bin/logstash
unsupported Java version "10", defaulting to 1.7

java -XshowSettings 2>&1 | grep java.version
java.version = 10.0.2
java.version.date = 2018-07-17

dpkg -l | grep logstash
logstash 1:6.5.0-1

Would you please at least get rid of the stupid check and just try to take whatever java is offered? because it just might work; whereas defaulting to ancient versions sure does not.

This still looks broken. I am running a slightly newer version of Logstash and still seeing the same errors.

I am still getting this error in java version 12.

$ gem install bundler

Same here.
