> There are few possible cleanups in java.desktop related to legacy StringBuffer usages:
> 1. In few places StringBuffer can be replaced with plain String concatenation.
> 2. StringBuffer can be replaced with StringBuilder. StringBuilder has better performance as it is not thread-safe.
> 3. There are few places where result of string concatenation is passed to StringBuffer.append method. Using separate `.append` calls is more clear.
> 4. In few places primitives are unnecessary converted to String before `.append` call. They can be replaced with specialized methods (like `.append(int)` calls.
