I'm trying to get the disassembly view working on a VSCode debug adapter, but it's not working. It's setting cap.supportsDisassembleRequest = true at initialization, and the stack frames it's returning have instructionPointerReference set. The "Open Disassembly View" context menu doesn't show up in the editor or when right-clicking the stack frame.

It turns out that only supportsDisassembleRequest matters for making the menu item appear. The problem was a bug in Microsoft's Java Debug Server.

The JSON for the initialize response was double-nesting the body:

{
  "success": true,
  "request_seq": 1,
  "command": "initialize",
  "body": {
    "body": {
      "supportsReadMemoryRequest": true,
      ...

Instead of setting the response body to an InitializeResponseBody, I had to set it directly to the Capabilities object to avoid the nesting.
