The type 'java.lang.String' in metadata shouldn't include internal type.

Type of char[] and int in java.lang.String is unnecessary.

@lexburner Then what is the properties of java.lang.String? What about null?

I can help with this issue.

@moriadry Consider 'java.lang.String' as a base type like int、double. Don't need any properties.
