Я использую Shibboleth IDP с контейнером сервлетов Jetty 9.4.12, и Jetty как-то предупреждает меня следующим образом:

Кажется, эти классы используются в javax.json-1.0.4.jar иjavax.json-апи-1.0.jar.Есть идеи, почему Джетти хочет предупредить их?

Это предупреждение выдается во время сканирования байт-кода для аннотаций при запуске веб-приложения.

Наличие нескольких версий одного и того же класса является источником ошибок и неправильного поведения.

В вашем случае у вас есть 2 версии одного класса, версии 1.0 и 1.0.4, как видно из имен файлов JAR.

Поскольку ClassLoader не имеет ожиданий порядка загрузки файлов JARи требования, это возможноЕсли выполнение одной и той же WAR в разное время приведет к разному поведению.

Jetty не может определить, насколько серьезна проблема с дублирующимися классами, решать вам.Jetty может выдавать это предупреждение только для распространенной поведенческой проблемы в веб-приложениях.

Чтобы устранить эту проблему, необходимо исправить полученный WAR-файл, включив в него только 1 копию каждого класса.
