Why hash codes in SymbolTable mismatching java_lang_String::hash_code for extended characters in Open JDK?

Issue

• SA: hash codes in SymbolTable mismatching java_lang_String::hash_code for extended characters.
• Can't use the SA if the target application contains a symbol which uses a non-ascii character.
• The SA tool will fail with an error, the JVM itself and the SA having calculated different hashes for
  such Strings.
