RE: [External] Cs studio cannot load model form

["Leblanc, Gregory via Tech-talk" <tech-talk at aps.anl.gov>]

Wyatt,

 

I was able to fix this error by running ‘sudo dnf update’ and then ‘sudo dnf install java-11-openjdk’ .  I think somehow the headless version of java got installed and one of the rolling updates to java was broken on centos 9 stream.

Hi, this morning I wanted to run cs studio I was originally using the latest snapshot. however, my Java Runtime was not up to date and could not recognize class file version 61.0 and could only recognize up to 55.0. I decided to switch to an official release of cs-studio so i would not have to worry about updating things.

 

this is the current configuration I have

 

installed location:      /home/saunders/cs_studio/Phoebus-4.7.3-linux/product-4.7.3

current user directory:   /home/saunders/cs_studio/Phoebus-4.7.3-linux/product-4.7.3

java home:            /usr/lib/jvm/java-11-openjdk-11.0.20.1.1-2.el9.x86_64

cs studio version:       4.7.3

java version            Oracle Corporation 11.0.20.1+1-LTS

java FX vesion          19+11

 

cs studio will now open but when i try to run one of the .bob files to test one of my displays i get the following error pop up with the following text

 

cannot load model from

/home/saunders/cs_studio/vacumeguagetest.bob

could not initialize class java.awt.Color

java.lang.NoClassDefFoundError: could not initialize class java.awt.Color

this is the case for any of the displays I try and run including the displays that come with the program including the home display. If anyone has any insight into what is going on here please let me know
