bug: The bug report is not correct, but there is nonetheless a related
underlying bug where IllegalAccessError fails to be thrown.
Question #1, is this a corelibs bug? It was filed against compiler, but the
fix is in the jdk classes, but it is MethodHandle code.
Question #2, what's the best way to write a jtreg test suite that requires
incompatible class files, that could not result from a single javac compilation?
Question #3, the message(s) attached to the exception are not the same in all
cases:
a. IllegalAccessError's been caught java.lang.IllegalAccessError: member is
private: MethodSupplier.m()void/invokeVirtual, from MethodInvoker
b. IllegalAccessError's been caught java.lang.IllegalAccessError: tried to
access method MethodSupplier.m()V from class MethodInvoker
c. IllegalAccessError's been caught java.lang.IllegalAccessError:
d. IllegalAccessError's been caught java.lang.IllegalAccessError: tried to
access method MethodSupplier.m()V from class MethodInvoker
The difference between a. and c. above (and these are the two that change under
this fix, the code the execution definitely intersects at the fix) is:
a = Class.forName("MethodInvoker").getMethod("invoke").invoke(null);
c = MethodInvoker.invoke();
yet one has the message copied from the underlying IllegalAccessException (not
IAError) and the other does not.
