  "message": "Use arraycopy to create enum values array in enum unboxing\n\nThis changes such that a shared utility class now contains (n being the largest enum value of any unboxed enum):\n\n  public static final synthetic $VALUES \u003d\n      new int[] { 1, 2, 3, ..., n };\n\nAccesses to MyEnum.$VALUES and calls to MyEnum.values() are rewritten to MyEnum$LocalUtility.values() (m being the largest enum value of MyEnum):\n\n  public static final synthetic values() {\n    int[] result \u003d new int[m];\n    System.arraycopy($VALUES, 0, result, 0, m);\n    return result;\n  }\n\nThis returns a copy of the underlying $VALUES array when accessing it via a field read. The $VALUES array generally only has a single use, which is followed by a call to clone(). This CL therefore identifies the call to clone() and removes it.\n\nAs a result of this, MyEnum.$VALUES \u003d\u003d MyEnum.$VALUES will return false (but Arrays.equals(MyEnum$VALUES, MyEnum$VALUES) is true). If this turns out to be a problem, we can consider disabling enum unboxing of enums that have unsupported reads of $VALUES.\n\nChange-Id: I543fb1b73bf34faa12486d00137ca1d0d10cf863",
