A DESCRIPTION OF THE PROBLEM :
In the test case we recursively called the sum() method, but sometimes it executed correctly, but sometimes a StackOverflowError was caught. When -Xint is set, it is executed normally.
We've uploaded test cases that reproduce behavioral differences to the Google Drive, which can be found at the URL(https://drive.google.com/file/d/1rYZrt6vciO_0MWG_U-l4ScbTp5pwEWjT/view?usp=sharing).
