| This rule finds concurrent calls to StringBuffer.append where String literals
are used It would be much better to make these calls using one call to
.append
example:
StringBuffer buf = new StringBuffer();
buf.append("Hello");
buf.append(" ").append("World");
This would be more eloquently put as:
StringBuffer buf = new StringBuffer();
buf.append("Hello World");
The rule takes one parameter, threshold, which defines the lower limit of
consecutive appends before a violation is created. The default is 1.
