String javaVersionName = System.getProperty("java.version");// J2SE SDK/JRE Version String Naming Conventionboolean isPreRelease = javaVersionName.contains("-");if (isPreRelease && javaVersion == 61.0)

{ System.err.println("Unsupported Java detected (" + javaVersionName + "). You are running an outdated, pre-release version. Only general availability versions of Java are supported. Please update your Java version."); return; }

 

openjdk 17-internal 2021-09-14 is a fully featured, fully functioning version of openjdk 17.

 

Even though the openjdk version is named as "17-internal", with the character "-" in the version name does not mean that it is a pre-release version of Java and that CraftBukkit can not run with that OpenJDK verion.

Please fix this so that openjdk 17-internal works with CraftBukkit without issue.

As a workaround use proto-distro on Termux to run a full Linux distro with updated Java versions.

Comment by md_5 [ 31/Aug/23 ]

This is a violation of https://www.oracle.com/java/technologies/javase/versioning-naming.html which explicitly states: "A dash "-" separator is used to indicate a non-GA (non-FCS) release.

A GA (FCS) product version or build identifier must not contain a dash ".
