Делаю диаграмму с помощью JFreeChart, диаграмма отображается нормально, если раскомментить кусок кода внизу, то это можно будет посмотреть.
Далее эту диаграмму нужно отправить по емайлу.
Использую апачевский CommonEmail.
Все хорошо до тех пор пока размеры картинки небольшие. 200 х 200 смогло отправить. Но как только размер увеличиваю до определенного размера (мне в идеале надо будет 1024 х 768), вылетает ошибка:

Exception in thread "main"
Process finished with exit code 1
Подозреваю что это связано с тем что я все это дело тестирую на своем буке дома, инет у меня очень тормозной, т.к. gprs и через некоторое время вылетает ошибка. Можно как-то это обойти и принудительно поставить долгое ожидание? Или дело не в этом? У заказчика интернет шустрый, таких проблем по идее быть не должно. Но.... Это очень важный аспект, email должен быть отправлен 100%, поэтому возможный баг надо искоренять заранее. Очень прошу помочь всех, у кого какие идеи есть, пусть они даже будут глупые :)
