java.io.IOException: Cannot run program "bash": posix_spawn failed, error: 13 (Permission non accordée) 
Possible reasons:
  - Spawn helper ran into JDK version mismatch
  - Spawn helper ran into unexpected internal error
  - Spawn helper was terminated by another process
Possible solutions:
  - Restart JVM, especially after in-place JDK updates
  - Check system logs for JDK-related errors
  - Re-install JDK to fix permission/versioning problems
  - Switch to legacy launch mechanism with -Djdk.lang.Process.launchMechanism=VFORK
