我遇到了以下javac编译失败,其中javac无法识别具有公共枚举的静态嵌套类上的注释.一旦我将枚举移出静态嵌套类,就解决了编译错误.有谁知道为什么javac失败了？这是一个java编译器错误吗？还是有一个我不知道的java细微差别？

下面是一个独立的测试用例.

无法编译:

package test;

import test.AnnotationBug.NestedClassWithEnum.ParticipantType;

import lombok.Data;
import lombok.NoArgsConstructor;

import com.googlecode.objectify.annotation.Embed;

public class AnnotationBug {

  ParticipantType type;

  @Embed
  @Data
  @NoArgsConstructor
  public static final class NestedClassNoEnum {
  }

  @Embed
  @Data
  @NoArgsConstructor
  public static final class NestedClassWithEnum {
    ParticipantType type;

    public enum ParticipantType {
      ORGANIZER,
      REGISTERED,
      WAIT_LISTED
    }
  }
}

编译输出:

$ javac -classpath /home/avaliani/projects/jars/objectify-4.0b2.jar:/home/avaliani/projects/jars/lombok.jar  test/AnnotationBug.java
test/AnnotationBug.java:20: error: cannot find symbol

  symbol:   class Embed
  location: class AnnotationBug

我正在尝试扩展angular-ui tabset功能,我遇到了包装它的问题.

这个plunker是未包装的tabset指令:

这个plunker包含我第一次尝试包装tabset指令:

最初的包装方法是直接包装.但是......我在替换模板中引入了额外的div,以避免"多个指令要求隔离范围"和"多个指令要求转换"角度错误并确保发生转换.

关键代码段:

.directive('urlTabset', function() {
  return {
    restrict: 'E',
    transclude: true,
    replace: true,
    scope: {
      tabManager: '='
    },
    controller: [ "$scope", function($scope) {
      var tabManager = $scope.tabManager;
    }],
    template:
      '<div>' +
        '<tabset>' +
          '<div ng-transclude>' +
          '</div>' +
        '</tabset>' +
      '</div>'
  };
})

.directive('urlTab', function() {
  return {
    require: '^urlTabset',
    restrict: 'E',
    transclude: true,
    replace: true,
    scope: { tabName: '@' },
    link: function(scope, element, attrs, urlTabsetCtrl) {
    },
    template:
      '<div>' +
        '<tab>' +
          '<div …
