我用谷歌搜索并在这里找到了一个可能的解决方案：“一个最小的解决方法是添加 -XX:LoopUnrollLimit=1 作为参数。” 问题是我不知道在哪里添加这个参数以及如何添加它。任何人都可以帮助我吗？

i don't know if this solution applies to every one or not, but i managed to solve this by updating my eclipse from indigo to kepler.
我不知道这个解决方案是否适用于每个人，但我设法通过将我的日食从靛蓝更新到开普勒来解决这个问题。

In linux mint 16, for me, the solution was change the eclipse theme from GTK to Classic and write in eclipse.ini this:
在 linux mint 16 中，对我来说，解决方案是将 eclipse 主题从 GTK 更改为 Classic 并在 eclipse.ini 中写入：
-Dorg.eclipse.swt.browser.DefaultType=mozilla
-Dorg.eclipse.swt.browser.DefaultType=mozilla

This error log looks as mine that I received when I've tried to open the Eclipse Marketplace. The Eclipse simply closed after that. My OS is the Linux Mint Derbian and I'm working with Eclipse Luna 4.4.1. I found this tip on the Derbian's forum and it worked for me. Re: Eclipse Luna Crashed on XFCE
这个错误日志看起来是我在尝试打开 Eclipse Marketplace 时收到的。之后 Eclipse 就关闭了。我的操作系统是 Linux Mint Derbian，我正在使用 Eclipse Luna 4.4.1。我在 Derbian 的论坛上找到了这个提示，它对我有用。 回复：Eclipse Luna 在 XFCE 上崩溃
I add the line to eclipse/eclipse.in:
我将这一行添加到 eclipse/eclipse.in：
--launcher.GTK_version
2
Hope it works for you too.
希望它也适用于你。
