Warn при компиляции(Lucera 2)

[Natzugen 172]

Привет всем, мне очень интересно данное предупреждение при компиляции Луцера 2. Компилируется без крит ошибок но варны меня беспокоют.

Заранее спасибо. За хороший ответ будет плюсик

JDK 8 должны решить эти проблемы

[Meeero 38]

Или как вариант 1.7

[amatory91 87]

might not be supported in releases after Java SE 8

8 ява не поддерживается

[Natzugen 172]

Я так и понял что не поддерживается данная версия но просто хотел бы узнать все эти ошибки связанны с JDK 8 ??

[amatory91 87]

Да все верно, именно из-за нее.

[Natzugen 172]

Спасибо решил проблему изменением JDK 8 на 7.
