8153666: Optimize Formatter.formatMessage
Summary: This patch brings a small optimization that removes needless synchronization in Formatter.formatMessage. It also fixes the code that decides whether to call MessageFormat, and brings a small clarification to the API documentation on the conditions when that will happen.
