Comment (by breun):

 I'm not 100% sure, but I think that may be because the license is set to
 `GPL-2+`, and that is not considered redistributable by MacPorts. OpenJDK
 is licensed under GPL 2 with classpath exception (see
 https://github.com/openjdk/jdk21u/blob/master/LICENSE and
 https://github.com/openjdk/jdk21u/blob/master/ADDITIONAL_LICENSE_INFO).

 On what version of macOS do you get this build error?
