tern with java 9 or higher

[maassg]

Any tern script when run with java 9 or higher gives the following:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.ternlang.core.type.index.FunctionGenerator (file:/opt/.install/java/tern/tern.jar) to method java.lang.Object.finalize()
WARNING: Please consider reporting this to the maintainers of org.ternlang.core.type.index.FunctionGenerator
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Ill put in a fix for this but you can effectively ignore it, its just indexing finalize().
