Bug Report

Current Behavior

When create BoundedPoolConfig with maxTotal = -1 and try to acquire a connection from pool throws java.util.NoSuchElementException: Pool exhausted.

Documentation says:

        /**
         * Configures the maximum number of objects that can be allocated by the pool (checked out to clients, or idle awaiting
         * checkout) at a given time. When negative, there is no limit to the number of objects that can be managed by the pool
         * at one time.
         *
         * @param maxTotal maximum number of objects that can be allocated by the pool.
         * @return {@code this} {@link Builder}.
         */
        public Builder maxTotal(int maxTotal)

Expected behavior/code

To have a Pool able to acquire connections with no limit.

Environment

• Lettuce version(s): [6.1.5.RELEASE]
• Redis version: [6.2.3]
