A DESCRIPTION OF THE PROBLEM :
When I compile the following test case, instead of successfully generating the .class file, I get an assertion error with the error message as shown in the Output content. Could you please tell me what is the cause of this situation?
Test case：
public class MyJVMTest_13160 {
  
    static void foo() {
        Integer i = 100;
        do {
            return;
        } while (i++ < 10);
    }

    public static void main(String[] args) {
        foo();
    }
}
Output：
An exception has occurred in the compiler (1.8.0-internal). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates. Include your program and the following diagnostic in your report. Thank you.
