#141 JXplorer only working up to Java8 ?

[birdofpray]

Hello guys,

just wanted to try out JXplorer, but didn't have Java installed yet. So I did "sudo apt install openjdk-9-jdk-headless" (I'm on LinuxMint, and this was one of the recommendations the system gave me, I picked the JAVA9 because it's the most recent one for my OS).

Then "chmod +x jsxplorer.sh" and "./jsxplorer.sh console". This is what I get:

starting JXplorer...
java -Dfile.encoding=utf-8 -cp .:jars/:jasper/lib/ com.ca.directory.jxplorer.JXplorer
logging level set from config to: WARNING with 0 parents=true

*** unable to load new security provider: com.sun.net.ssl.internal.ssl.Provider
java.lang.IllegalAccessException: class com.ca.directory.jxplorer.JXplorer cannot access class com.sun.net.ssl.internal.ssl.Provider (in module java.base) because module java.base does not export com.sun.net.ssl.internal.ssl to unnamed module @79efed2d

A fatal error has been detected by the Java Runtime Environment:

SIGSEGV (0xb) at pc=0x00007feb9fbdd009, pid=8717, tid=8746

JRE version: OpenJDK Runtime Environment (9.0) (build 9-internal+0-2016-04-14-195246.buildd.src)

Java VM: OpenJDK 64-Bit Server VM (9-internal+0-2016-04-14-195246.buildd.src, mixed mode, tiered, compressed oops, g1 gc, linux-amd64)

Problematic frame:

C [libjava.so+0x1d009] JNU_GetEnv+0x19

It seems JXplorer is only working up to Java8, as of Java9 there is JPMS involved which changed the whole package/module system of Java.

Any chance that this would be enabled for current Java versions?

Kind regards,
Ralf

Hi Ralf,

thanks for letting me know - I'm still running java 8... I'll check it out.

As an aside, you mention installing 'headless' java - JX is a UX heavy application, so I doubt it will run in headless mode. I don't think that's related to the problem of the SSL class not being available, but it would be worth running with the 'normal' java to make sure...
