'StringBuilder' without initial capacity
Reports attempts to instantiate a new StringBuffer or StringBuilder object without specifying its initial capacity.
If no initial capacity is specified, a default capacity is used, which will rarely be optimal. Failing to specify the initial capacity for StringBuffer may result in performance issues if space needs to be reallocated and memory copied when the initial capacity is exceeded.
Example:
// Capacity is not specified
var sb = new StringBuilder();
