我最近安装了ubuntu16.04(自动更新到这个版本),我通常用Java开发,而且我知道eclipse,所以我安装了它,一切都很好。
我配置了所需的一切(Java路径、JDK...没有什么特别的),除了Eclipse UI之外,工作正常。
UI冻结每次我创建一个项目(虽然项目创建正确),每次我运行任何程序(虽然程序运行,因为它应该(并不总是正确的xD,但这是我的错)),并与许多其他任务。
知道为什么会发生这种情况吗?更好的是,如何解决它?
我还仔细检查了我使用的JRE(因为我发现人们对开源软件有问题),我使用甲骨文的版本(现在不确定名称,抱歉,版本8)。上面的所有内容都是64位版本。
编辑:我忘了说我用的是Mars版本。还有,我刚安装了NetBeans(8. 1),完全一样的问题,然后我以为是图形驱动程序的问题,又安装了一次,还是一样的问题。不知道现在该怎么试。
**更新:**检查日志文件。我没有发现任何异常,但可能缺少一些东西:

Linux上的Eclipse UI默认使用GTK 3来显示内容,但是我发现经常有问题,我不确定这是否是问题的根源,但是您可以通过使用环境变量设置禁用GTK 3支持来检查:
export SWT_GTK3=0
。但是,在您发现问题的根源之前,我不会永久打开它。bqujaahr2#
我已经发现了问题所在,正如佐尔坦和丹指出的,GTK就是问题所在。
解决方案:(仅在Eclipse上测试):
1.转到“窗口〉首选项〉常规〉外观”。
1.更改“GTK”主题为您喜欢的任何其他主题。
这为我解决了问题。

您应该生成eclipse进程的java线程转储,如下所示:
1.确定进程ID:
识别代表eclipse示例的行,并记住该行的第一个数字,即进程id。
1.使用进程ID触发线程转储:
这样你就可以得到
JVM
中每一个线程的堆栈跟踪,从这里你就可以知道为什么你的程序没有运行。hxzsmxv24#
打开https://bugs.eclipse.org/bugs/show_bug.cgi?id=492829以跟踪此问题,因为SWT /GTK 3交互中可能存在漏洞。

我认为这个问题发生在Eclipse的早期版本。我尝试了Eclipse Mars的Java和J2ee版本。我检查了 neon 版本;这个问题没有发生。2 Eclipse没有冻结。

在eclipse.ini中,将heap增加到1GB似乎解决了我的问题。您可以在Go to Window〉Preferences〉General中查看启用heap usage后使用了多少heap
信息显示在UI

eclipse.ini更改
希望这会有帮助。(我的是256米,增加到1024米--有些时候我可以看到它超过600米)
