      Description

      A DESCRIPTION OF THE PROBLEM :
      The issue mentioned in JDK-8213538 has been fixed, but it still exists if the -xcomp option is added. In JDK8, jdK17 there is no error, and in JDK17 there is a prompt that the value range must be greater than 4.

      $ java -Xcomp -XX:MaxVectorSize=2 -version
