Hello Shaojin,
I think your proposal is reasonable. These arrays are never mutated. Meanwhile
I see some declarations like int A[] in CharacterData00, would be nice if you
can convert those declarations to like int[] A too.
Regards,
Chen

Subject: Add @Stable to java.lang.CharacterDataLatin1 and other CharacterData
classes
Classes such as java.lang.CharacterDataXXX have multiple static final arrays,
which will not be modified. We should add @Stable to provide information to the
optimizer.
such as
```java
class CharacterData00 {
@Stable static final char[] X =
@Stable static final char[] Y =
@Stable static final int[] A =
@Stable static final char[] B =
}
```
