如何禁用 IntelliJ IDEA 烦人的检查 (JAVA)

Question

version: IntelliJ IDEA Community Edition 2020.1.2

There is an error that occurred in Intellij but Eclipse not.

According to the below code, the variable is StringBuilder and it's okay to append an integer or an int by the book.

But why Intellij shows me this error? How to disable the inspections and make the red line disappeaded.

By the way, that code looks fine in eclipse.

my sameaple code

public class test123 {
    public static void main(String[] args) {
        StringBuilder msg = new StringBuilder();
        Double rate = new Double(123);
        msg.append(rate == 0 ? (rate == 0 ? 0 : "-" + rate) : String.valueOf(Math.round(rate*100)).replace("0", "") + "折");
System.out.printf("yyuu:"+msg.toString());
    }

}

The issue seems to be the IntelliJ IDEA bug, javac and eclipse compilers compile the code without errors, though Editor shows the error.

Please follow the issue created for the bug: https://youtrack.jetbrains.com/issue/IDEA-244854
