Confusing argument to varargs method
Warning
New
Last modified: 03 December 2024 Reports calls to variable arity methods that have a single argument in the vararg parameter position, which is either a null
or an array of a subtype of the vararg parameter. Such an argument may be confusing as it is unclear if a varargs or non-varargs call is desired.
Example:
String[] ss = new String[]{"foo", "bar"};
System.out.printf("%s", ss);
In this example only the first element of the array will be printed, not the entire array.

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
