Наше приложение использует Spring. Моя цель состоит в том, чтобы при запуске системного теста я мог инструментировать класс при загрузке класса. Я использую собственный загрузчик классов для инструментария классов в проекте.
instrumenting class 'application.framework.gaeb.util.GaebDataExchangePhase'
Когда я запускаю тест, я получаю NPE.

Если я использую свой собственный ClassLoader, но не сам определяю класс, но используйте только super.loadClass, тогда проблем не будет. Но использование моего собственного loadClass сообщит об ошибке.
