我正在使用Eclipse 4.4.1，我总是遇到这个错误，我无法使用eclipse。

有没有办法解决它？

Answer 1

我在安装https://extensions.gnome.org/extension/779/clipboard-indicator/后注意到了这种行为。你也安装了这个扩展吗？当我禁用此扩展（并重新启动gnome-shell）时，Eclipse中的异常消失了。你能证实一下吗？

我在这里做了一个错误报告：https://bugs.eclipse.org/bugs/show_bug.cgi?id=449902。

Answer 2

您不知道计算机上有多少内存，但您很可能指定了过大的内存要求。

检查这个优秀的答案：

What are the best JVM settings for Eclipse?

根据您的设置，我相信您需要1GB的可用内存才能启动，如果加载大型项目，可能会使用更多内存。

如果这没有帮助，那么我也注意到异常发生在一个似乎与剪贴板传输相关的方法中。您的剪贴板中是否有可能包含非常大的数据集？这只是一个猜测，我不知道Eclipse为什么要在加载时从剪贴板传输数据。
