    Variable ERR_INVALID_MAX_WORKERSConst

    ERR_INVALID_MAX_WORKERS: string

    Invalid maxWorkers error

    Thrown by configure when Configuration#maxWorkers is not an integer greater than 0. A value lower than 1 used to deadlock ZipWriter#add for ever, since no entry could start and none could release the next one. Pass Configuration#useWebWorkers set to false to compress and decompress data in the main thread instead.
