힙 스페이스 오류 : 오류의 원인을 파악할 수 없습니다.

Question

이 코드의 코드를보고 메모리 누출이 있는지 확인하는 사람이라면 지나치게 크지 않지만 시간이 지나면 계속해서 충돌하고 사용 방법을 모르겠습니다. Viualvm이 며칠 동안 읽고 있었지만 힙 덤프에서 무엇을 찾고 있는지 가장 작은 아이디어를 얻지 못했습니다. 도움을 주셔서 감사합니다. PS 저는 Muchg 코드에 멀리 게시되었음을 알고 있지만 문제가 어디에서 발생하는지 바를 수 있도록 무엇을 해야할지 모르겠습니다. 그것이 도움이되면 전체 프로그램을 이메일로 보내면 살펴볼 수 있습니다. 도움을 주셔서 감사합니다.

Answer 1

오늘 그것을 해결했습니다. 나는 이전 방법에서 이미지 패널을 제거하지 않았다는 것이 밝혀졌습니다. Aso는 내가 그들을 다시 칠할 때 나는 오래된 것들에 그림을 그렸고 오래된 것들이 여전히 거기에 있다는 것을 알았습니다. 따라서 업데이트중인 모든 패널에 대해 removeall ()을 추가해야했으며 힙 스택 오류없이 프로그램이 정상적으로 실행되었습니다.
