It's a funny 'public' review when the specification requires me to
agree to a license, specifically the 'License Agreement for JSR-000292
Supporting Dynamically Typed Languages on the Java Platform 0208
Public Review Draft'. IANAL, but some of the terms of that would seem
to conflict with the GPL license of the OpenJDK implementation,
notably '(i) developing implementations of the Specification for your
internal, non-commercial use'.
Is any of this available publicly without draconian licensing and clickthroughs?
