GraalVM: Run Programs Faster Anywhere
Am I correct in reading the license in Github that this is all GPL?  Albeit GPL2 but still not some Oracle proprietary license."One VM to rule them all" reminds me of Parrot VM (for Perl 6).  Looks like development slowed down a year or two ago.  Back then, it got me excited as it looked like the "open source community" alternative to "Big Corporate Java".https://en.wikipedia.org/wiki/Parrot_virtual_machine
