Proposed fix for: https://bugs.openjdk.java.net/browse/JDK-8142882
http://cr.openjdk.java.net/~rasbold/8142882/webrev.00/ Don't pre-dispatch the receiver of a DirectMethodHandle, as it may allow a protected method to be accessed. This fix is a subset of the change for JDK-8050166 <https://bugs.openjdk.java.net/browse/JDK-8050166>, which is already in jdk8 and jdk9. The change causes the an NPE to be thrown when a protected MethodHandle is called via invoke(). An additional backport of JDK-8016839 <https://bugs.openjdk.java.net/browse/JDK-8016839> is needed, if it is desired to that a proper IllegalAccessError is thrown instead of an NPE, as happens with jdk8 / jdk9.
