Possible regression (assert(_adapter == NULL) failed: init'd to NULL)

[John Rose]

It looks like this regression is due to a version mismatch.  The name "invokeVarargs" is no longer defined; it was replaced by "invokeWithArguments" and has been deprecated for some time (since bug 6981777, circa 10/2010).

I suspect the lambda prototype needs updating.  Also, we are in a transitional period now, since the java.dyn package is being renamed to java.lang.invoke.  That might be causing the lambda folks to hold back on backend updates.
