If c.s.s.u.Trees.isAccessible is called on a public innerclass, which is inside an inaccessible type, it returns true, although it should return false, in my opinion.

I have revision 248 checked-out from https://openjdk.dev.java.net/svn/openjdk/jdk/trunk, but I have some problems with the checkout, so it is possible that I run tests against an older 1.7 build.
Test case:
/*
 * @test
 * @bug 9999999
 * @summary Trees.isAccessible does not work correctly
