Known Issues #

  • On GraalVM 20.3 language REPLs, that migrated to JLine 3, will crash on startup when launched in the rxvt terminal emulator. It is a known bug in JLine that has already been fixed in the most recent version 3.15. Please consider upgrading JLine.

  • With macOS 10.15, Apple introduced new requirements for software notarization. The GraalVM distribution is not currently notarized and will be quarantined by default. To install GraalVM, you will need to run the following command to remove from quarantine:
    xattr -d com.apple.quarantine /path/to/GRAALVM_HOME
    
  • Due do the issue with the underlying platform Java Mission control freezes at startup on macOS. Because of that we removed the jmc utility from the distribution. For more information and workarounds please see the JMC known issues page.
