JDK-8011311 - Lambda: Support Private concrete methods in interfaces
Description
Reflection code is split across the JDK and the vm. Reflection generates code dynamically to speed up reflection processing after startup. The generated code needs to use invokespecial for private interface methods to match the JVMS specification.

Robert is adding a test to the jdk/test/java/lang/Method/invoke to go with the fix. The test uses asm. Many thanks.

ReflectInvokeprivaterepeat.java is a standalone test you can use. It depends on 1. SuperIwithDefault.java 2. SuperIwithDefaultChild.java -- javac all -- then patch SuperIwithDefault.class: change "public Method bar" to "private explicit Method bar" I also changed string from I.bar to "invoked private I.bar", but that could be changed in the original source.
