Severe Crash (possibly due to missing JAVA/CATALINA options)

[SavSanta]

Cant get this docker image to run

I basically get a similiar abandoned and then exception as is mentioned in the other issue.

I though the issue was it running out of memory so I used the really confusing and not to helpful official openOLAT installation documentation and see this page mentions that it may need the CATALINA_OPTS variable passed with certain limits. So i tried a few different ways to edit the setenv and exported variables to pass -Xmx1024m -Xms512m -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=. . That didnt have an effect. Java itself is pretty confusing between the environment variables so maybe it's suppose to be JAVA_OPTS or JRE_OPTS or something different but I wouldnt know.

Any ideas welcome! Though, to be honest I wanted to evaluate openOLAT but it really is quite tricky to get it to run so maybe I wont submit it for our organization. Though, I'd like to help in solving for the future users
