Issue https://bz.apache.org/bugzilla/show_bug.cgi?id=59923 updated the default validationInterval, however, the Javadoc on PoolConfiguration was not updated:


    /**
     * avoid excess validation, only run validation at most at this frequency - time in milliseconds.
     * If a connection is due for validation, but has been validated previously
     * within this interval, it will not be validated again.
     * The default value is 30000 (30 seconds).
     * @param validationInterval the validation interval in milliseconds
     */
    public void setValidationInterval(long validationInterval);
