Hi Jim, To be clear, there is no subscription required by Moonshine or Royale to use any JDK version. Moonshine, Royale, and OpenJDK are all free and open source. If you upgrade your JDK, it will fix this error.
The current 0.9.10 release of Royale requires JDK 8 minimum. And the nightly Royale 0.9.11 requires JDK 11 minimum. Based on the error you are receiving, it appears that you are running JDK 8 in Moonshine. The Moonshine SDK Installer should allow you to install a newer JDK. Alternatively, if you prefer to install JDKs manually, you can also open Moonshine's settings and configure a custom JDK path. Either option should allow you to upgrade from JDK 8 to a newer version, and this error will be resolved. -- Josh Tynjala Bowler Hat LLC <https://bowlerhat.dev> On Tue, May 14, 2024 at 4:09 PM Jim McNamara <jmcnamara10...@proton.me> wrote: > > Hi all- > > Is there a way besides compiling from source to get a newer openjdk > version for the sdk?
