JEP 259: http://openjdk.java.net/jeps/259
Javadoc for the proposed StackWalker API:
http://cr.openjdk.java.net/~mchung/jdk9/jep259/api/java/lang/StackWalker.html
A simple way to walk the stack:
StackWalker walker = new StackWalker(StackWalker.Option.CLASS_REFERENCE);
walker.walk((s) -> s.filter(f -> interestingClasses.contains(f.getDeclaringClass())).findFirst());
The current usage of sun.reflect.Reflection.getCallerClass(int depth) can be replaced with this StackWalker API.
Any feedback on the proposed API is appreciated.
