Incompatibility with Java 9 - JRE Path changed

[cthoyt]

PyJnius looks for the path

/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/jre/lib/server/libjvm.dylib

but the jre folder doesn't exist in this hierarchy anymore and it should look for

/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/lib/server/libjvm.dylib

Looks like this just needs a small change at https://github.com/kivy/pyjnius/blob/master/setup.py#L82 , but I'm not sure exactly what should be different (e.g. is this a new condition if framework has a certain value?). Would you be able to post the output of /usr/libexec/java_home?

[cthoyt]

I'm running Mac OS 10.13 with Java from the most recent brew cask install java.

$ /usr/libexec/java_home
/Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home

As a side note, in the past, with the -v option, you had to do /usr/libexec/java_home -v 1.8 but now you have to do /usr/libexec/java_home -v 9. Looks like they've committed to a new versioning scheme.

Hi @inclement, I'm just coming back to this now. Was this feedback enough to make an update?

Guys, any update ?

It's not just an OSX issue if you're using open-jdk the jre folder no longer exists. Any open jdk version >= 9 no longer has the jre folder. See http://openjdk.java.net/jeps/220 since java 9 the folder hierarchy was restructured. The jre/lib/amd64/server/libjvm.so path is no longer valid (

pyjnius/setup.py

Line 163 in 1cbfef2

lib_location = 'jre/lib/{}/server/libjvm.so'.format(cpu)

).

Just Ctrl+F for libjvm.so, but yeah, it's since 9:

https://packages.ubuntu.com/cosmic/amd64/openjdk-11-jre-headless/filelist

That bug will also affect the usage of Java >= 9 using the soon-to-be-released conda-forge builds: conda-forge/openjdk-feedstock#34, conda-forge/openjdk-feedstock#35, conda-forge/openjdk-feedstock#36
