Consider this layout: ``` MemoryLayout SEQ = MemoryLayout.sequenceLayout(5, MemoryLayout.sequenceLayout(10, JAVA_INT)); ``` And the corresponding offset handle: ``` MethodHandle offsetHandle = SEQ.offsetHandle(PathElement.sequenceLayout(), PathElement.sequenceLayout()); ``` The resulting method handle takes two additional...

Refactor code for computing denotable projection of types

3

The code reflection support needs a way to compute the closest fully denotable supertype of the type of an expression. To do this we build on [type projections](https://docs.oracle.com/javase/specs/jls/se25/html/jls-4.html#jls-4.10.5), but this...
