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.
