Jpa 当试图编织类时，EclipseLink抛出ArrayIndexOutOfBoundsException

我已经有了play框架应用程序（2.3.8），我为其提供了eclipselink-2.5.1.jar代理。在启动期间，我在日志中看到：

Weaver在尝试编织类时遇到异常 [我的一个JPA实体类]。例外情况是： java.lang.ArrayIndexOutOfBoundsException:30053

我如何调查问题的原因

可能有什么问题

更新： 因此，将日志记录更改为finest给了我一个堆栈跟踪：

但这对我帮助不大。

这看起来像EclipseLink在处理lambda表达式时使用的ASM处理器中的一个bug。EclipseLink 2.6中修复了该错误。

尝试使用静态编织器，并将日志设置为“最佳”，看看是否出现异常。请参阅

dev

（使用

activator run

）或仅在

prod

中是否存在此问题？您的配置是否与此处描述的类似：实际上我不确定如何在dev中提供代理，因此我不确定是否存在此问题。在生产环境中，我为我的开始脚本提供了-J-javaagent:/somewhere/org.eclipse.persistence.eclipselink.jar，这就是问题所在。至于配置，它与链接中的配置非常相似（我使用postgresql而不是mysql）。顺便说一句，我没有提到它-持久性工作正常，应用程序启动-但是有这些错误，编织可能不会发生。更新EclipseLink似乎解决了问题。这个问题很可能是由您提到的bug引起的（但我并没有仔细研究）。
