Build Identifier: 3.7

Code that is of the form:
public String foo() {
  StringBuffer buffer = new StringBuffer();
  buffer.append("stuff");
  return buffer.toString()
}

can be promoted to StringBuilder (if the compiler compliance is >= 1.5) without any loss of function. An informational/warning dialog noting the construction and destruction of a StringBuffer inside a single method (i.e. does not escape through field, inner class binding etc.) is guaranteed to be handled by a single thread and so can use the StringBuilder which doesn't have synchronized semantics.

Reproducible: Always
