Improperly specified VM option 'MaxRAMPercentage=50' #99

Closed danielvartan closed 3 months ago

Hi,

I'm trying to run nlrx "Get started" example, but I'm getting the following error.

It seems like an internal issue. Any ideas?

Error

Improperly specified VM option 'MaxRAMPercentage=50'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Error in (function (.x, .f, ..., .progress = FALSE)  :

Either the simulation did not run or crashed, check the debugging section in ??run_nl_all() for help.

The issue appears to be related to the JDK (Java Development Kit) version.

I uninstalled version 8u411 and installed the most recent one (22.0.1), and it worked fine.
