无法获取状态更改锁

Steffi S .:

我们的产品使用的是SWT的最新生产就绪版本3.7.2。现在,既然没有人知道下一个Java版本会叫什么(他们怎么知道8 org.eclipse.osgi紧随7之后,就像是高等数学),我们被迫将3.7.2换成3.10.0,所以我们现在可以支持Java8。虽然这可能不是最好的主意,但从理论上讲应该可以。

当然,作为Eclipse Luna的主要问题,在启动应用程序时会出现一个“错误”(我猜大概有50%的时间):

Web上没有太多问题的信息,大多数问题是建议删除工作空间,但是大多数情况下,仅在启动Eclipse而不是最终应用程序时才会发生-尽管如此,我还是删除了工作空间和运行时文件夹。没有任何帮助。“错误”也将引发出口产品,但据我所知,一切仍然按预期进行。

有办法解决吗?如果没有,是否有办法隐藏这个愚蠢的异常(暂时禁用日志记录,清除日志,无论如何,我都不挑剔)?

BJ Hargrave:

看起来框架启动启动了simpleconfigurator,它试图再次启动框架。框架检测到此递归并抛出异常以对其进行转义。问题似乎出在simpleconfigurator中,尝试启动正在启动它的框架。
