Bug report: JavaScript arrays are not coerced into Java arrays when calling Java functions that expect arrays

[Jim Laskey (Oracle)]

After consideration and from my own experiences, I'm going to add as a feature request.  However, code freeze is next week, so it's extremely likely this will not show up until first non-security update.  

JDK-8026113

Cheers,
