      Description

      When one tries to shrink a buffer which minimal capacity is set to 0, and set the size to 0, it enter into an infinite loop.

      This is due to this loop :

              for (;;) {
                  if (newCapacity >>> 1 < minCapacity) {
                      break;
                  }
      
                  newCapacity >>>= 1;
              }
      
      

      Fixed with commit : 80af8c36890f7a25beb35fe01c2b62650414cf0e

      Thanks to Erick Lichtas for the report.
