7u45 웹 스타트의 새로운 교착 상태 버그?

자바 7u45에서 재미는 계속 제공합니다. 이번에는 webstart 내의 교착 상태입니다. 이것은 매우 일관되게 (매번) 대형 응용 프로그램 (~ 100 병)을 시작합니다.7u45 웹 스타트의 새로운 교착 상태 버그?

누군가 다른 사람에게이 문제를 신고하거나 해결 방법을 알고 있습니까? 1.7.0_40으로 되 돌리는 것 외에는? 나는 내 댓글에 언급 된 버그 보고서가 지금 받아 들여졌다

JVM/JRE/JDK 버그를 발견하면 Oracle에보고하십시오. http://www.oracle.com/technetwork/java/javase/bugreports-140511.html –

내가 계획했지만 버그 보고서에 대한 oracle의 의견은 단지 "감사합니다." 응답이 없으므로 '받아 들여야'버그를 볼 수 없습니다. 이 부분을 조금 더 살펴보고 7u40과 7u45 사이에서 deploy.jar에서 변경된 것을 찾을 수 있는지 확인했습니다. –

버그는 7u40과 7u45 사이의 deploy.jar의 CacheEntry 클래스에서 getJarFile()에 추가 된 새로운 코드 블록에서 비롯됩니다. 지금 버그를 제출했습니다. 운이 좋으면 버그를 공개 할 수도 있습니다. (Larry의 말을 듣고 있습니까?) –

감사합니다.

ID는 프로세스의 일부로 변경된 것처럼 보입니다. JI- 네임 스페이스에서 JDK- 네임 스페이스로 이동되었습니다. https://bugs.openjdk.java.net/browse/JI-9007571은 이제 https://bugs.openjdk.java.net/browse/JDK-8027029으로 리디렉션됩니다. 이 문제는 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8027029에서도 볼 수 있습니다.

수정 사항은 1 월에 7u51에 포함되도록 토론중인 것 같습니다.

스택 추적은 유사합니다. 교착 상태 자체는 동일합니다. 이 경우에는 페이지에 두 개의 애플릿이 동시에로드됩니다.
