InaccessibleObjectException when executing any algorithm #421

Closed adamyalei closed 3 years ago

adamyalei commented 3 years ago

Hi, I got this error when I tried to execute an algorithm. I tried different ones with different input data and the same happened.

ERROR: HHH000142: Javassist Enhancement failed: de.metanome.backend.results_db.Result
java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @11739fa6

The task, on the frontend, shows as aborted and no result file was generated.

I did not find any similar error in the troubleshooting so I'm not sure if it's a bug or if I'm doing something wrong. I would appreciate help to solve this.

Currently using Java JDK 1.8 and Maven 3.6.3.
