Sorry about the issues with javadoc not rendering JLS links, and about specdiff being out of sync. Aside from those issues, some replies below: * FileChannel.map: I will use "size overflows the range of long" - but I still need separate condition to check that size >= 0 and offset >= 0 (otherwise nonsensical combos are still possible) * FunctionDescriptor::argumentLayouts: I've tweaked the javadoc of this methods to state that the returned list is immutable (I've looked at how MethodType::parameterTypes did that). * MemoryAddress - I will add "Might be negative" to the various dereference methods * MemorySegment::asOverlappingSlice - I will change return type to use Optional * I've added reference to C99 standard * MemorySession::equals - I've clarified the text w.r.t. asNonCloseable * MemorySession explicit vs. implicit close. I think there is some confusion here. The term "implicitly closed" has been used to denote a session that is closed automatically by a Cleaner. But I see how that creates tension with use of try with resources. I will try to simplify this area and just spec the behavior in terms of closeable sessions and non-closeable views.
