Warnings when running with -Xcheck:jni

[Scott Palmer]

I noticed several warnings coming from javaFX when I ran my app with
-X:check:jni

Is that something worth filing an issue over,or is it basically a known
thing and we don't particularly care?

E.g.:

WARNING in native method: JNI call made without checking exceptions when
required to from CallStaticObjectMethodV
