Some of it is discussed here: https://github.com/openjdk/panama-foreign/pull/617 Essentially, it is to avoid accidentally inheriting behavior from BufferBlob which we don't want. Also, BufferBlob currently expects a fixed-sized header (`sizeof(BufferBlob)`), while OptimizedEntryBlobs has fields, so we'd have to pass the real header size to the `BufferBlob` constructor, which is a bit messy. It felt better to just cleanly break away from BufferBlob. ------------- PR: https://git.openjdk.java.net/jdk/pull/7959
