после перехода на sdk 1.4.0 класс перестал компилироваться

[Алексей]

недавно обновил sdk с 1.3.7 на 1.4.0, после чего класс который работал
при 1.3.7 перестал компилироваться с такой ошибкой:
Unable to compile class for JSP:

использую Eclipse 3.5.2, SDK менял через свойства проекта

кто-нибудь может подсказать с чем это связано?
