원인은 hotswap agent가 hibernate plugin의 기본 탑재를 가정하여 기동하는데, 설치되어 있지 않았던 것이 문제 였던 것.

hotswap agent 의 설정에서 hibernate plugin을 disabled 목록에 추가하니 이상 없이 동작했다.

 

설정하는 부분은

Ctrl+Alt+S > HotSwapAgent > Disabled plugin 의 입력폼에 ‘Hibernate’ 라는 문자열을 입력 후 적용.

comma separated name list 라고 하는데, 저 Hibernate 라는 이름도 찍어서 맞췄을 뿐, 어디에 이름들이 정의되어 있는지 몰라서 답답하긴 하다.
