Hi folks, I understand that building Processing itself requires Oracle’s Java 8, but there is no mention of any restriction what can be used to build contributed libraries. ([https://github.com/processing/processing/wiki/Library-Guidelines](https://github.com/processing/processing/wiki/Library-Guidelines))

Is there any reason that building with OpenJDK 8 would be a problem? I’m using pure Java code.

No, they’re effectively the same thing. Just use OpenJDK 8. There isn’t even a current Oracle JDK 8 that Processing could bundle any more.
