Referencing inner classes in playJava doesn't use percent-encoded reference URI

[prouzpe3]

class A {
  private B b;
  class B {
  ...
  }
}

generates schema specification:

"A" : {
  "properties" : {
    "b" : {
      "$ref" : "#/components/schemas/A$B"
    }
  }
....

but $ should be encoded as %24

"A" : {
  "properties" : {
    "b" : {
      "$ref" : "#/components/schemas/A%24B"
    }
  }
....
