openjdk11-graalvm doesn't allow mirroring distfiles

[ryandesign (Ryan Carsten Schmidt)]

openjdk11-graalvm deliberately does not allow distfiles to be mirrored:

# This port uses prebuilt binaries; 'NoMirror' makes sure MacPorts doesn't mirror/distribute these third-party binaries
license          GPL-2 NoMirror

I don't understand the comment. Just because a port installs a binary doesn't mean we want to prohibit mirroring distfiles.

If the developers of this software prohibit redistribution, then yes we should prevent mirroring, but we should also prevent distribution of binaries.

Prohibiting mirroring distfiles causes fetch failure on older macOS versions:

Please check your other ports if similar changes are needed there.

I set this port to NoMirror because the binary archives used to be like 400+ MB per release and would be cached for each Darwin version. They have since been reduced to ~250 MB and the new platforms {darwin any} syntax could be used to only store the binary once for all Darwin versions.

/Library/Java/JavaVirtualMachines/openjdk11-graalvm/Contents/Home/LICENSE.txt says:

GraalVM Community Edition consists of multiple modules. The software as a whole, is released under version 2 of the GNU General Public License with the “Classpath” Exception. Certain modules of GraalVM Community Edition are released under separate and/or additional licenses, as follows: Graal.js is released under the Universal Permissive License (UPL) Version 1.0; Sulong – LLVM is released under a 3-clause BSD license.

Graal.js and LLVM modules are not included in this port at this time. I believe redistribution of these binaries should be allowed, but I'm no expert on this.

By the way, I'm also not sure if these binaries would work on Mac OS 10.9 if they could be downloaded. I can't find any info on which versions of macOS are supported in the ​installation documentation. Most OpenJDK-based distributions only support newer versions, but I don't know if that's because they don't verify correct operation on those legacy OS versions or if it actually doesn't work.

If you think NoMirror should be removed, I'm fine with doing that.

Replying to breun:

license NoMirror has nothing to do with whether we can distribute binary archives. It only relates to whether we can mirror distfiles.
