I Have a Question about J2V8

[kingkong3]

Hello, sir! I’m a beginner programmer in South Korea and I have three questions about J2V8.

First, how often V8 version of J2V8 is updated? Second, is J2V8 available on OpenJDK? If it is, upto how high version does it support? Third, is it possible for an individual to update V8 of J2V8? If it is, can I use all the latest ES features by only updating V8?

Thank you.
