I’m working with Geant4 10.07 on mac OS Catalina and I have installed “jdk” by mac port. Below the output from “java -version”:
openjdk version “15.0.1” 2020-10-20
OpenJDK Runtime Environment AdoptOpenJDK (build 15.0.1+9)
Eclipse OpenJ9 VM AdoptOpenJDK (build openj9-0.23.0, JRE 15 Mac OS X amd64-64-Bit Compressed References 20201130_124 (JIT enabled, AOT enabled)
OpenJ9 - 0394ef754
OMR - 582366ae5
JCL - ad583de3b5 based on jdk-15.0.1+9)
During the Geant4 installation I have set all the visualisation options as you can see here:
You have successfully registered the following graphics systems.
Registered graphics systems are:
OpenGLImmediateX (OGLIX, OGLI)
OpenGLStoredX (OGLSX, OGL, OGLS)
but when I run “java -jar HepRep.jar” I see:
Error: HepRApp was started with Java version 1.0 but requires version 1.4 or newer.
I’m sure that I have installed java 8.
Where is my mistake?
Thanks in advance.
