Hi @CamiloCastelblanco, the sun.misc were dropped in JDK9, but should be ok in JDK8 that is the one shipped with MatlabR2024a
Java Platform, Standard Edition Oracle JDK 9 Migration Guide, Release 9
Could it be that you changed the JRE that Matlab uses?
Run the command below to know which version of java is being used:
>> version -java
You can change the version with the function jenv
Set Java path for MATLAB - MATLAB jenv
